Bella has a bakery. She will use the bakery items at the right to make a gift basket worth $40. Bella wants the basket to have more than one of each bakery item. Show one way to make a gift basket.

What do I need to do to make a gift basket?

I need to be precise. I will decide how many of each item to put in a basket so the total is exactly $40.

Here’s my thinking…

How can I be precise in solving this problem?

I can

- correctly use the information given.
- calculate accurately.
- decide if my answer is clear and appropriate.
- use the correct units.

I will start with $40.

I know how many of each item is available.

3 wheat loaves × $4 = $12

$40 – $12 = $28

9 cinnamon buns × $2 = $18

$28 – $18 = $10

10 muffins × $1 = $10

$10 – $10 = $0

All calculations are correct. My gift basket has 3 wheat loaves, 9 cinnamon buns, and 10 muffins. The total is exactly $40.

Convince Me! Be Precise Is there another way to make a gift basket that totals exactly $40? Explain.

**Guided Practice**

**Be Precise** Use the graph on the previous page. Suppose Bella wanted to make a gift basket worth $25 instead. The gift basket must also have more wheat loaves than muffins. Show one way Bella can make the gift basket.

Question 1.

What given information will you use to solve?

Answer:

Given

Bella wants a gift basket worth of $25

She wants more wheat loaves than muffins.

Using the list of items in the Bakery and the cost of the items. I will calculate the cost of the items and compare with the basket worth.

Question 2.

Show and explain one way Bella can make the gift basket.

Answer:

Total worth of the gift basket = $25

Cost of Muffins = $1 each

Cost of Cinnamon Buns = $2 each

Cost of Wheat loaves = $4 each

Cost of 4 Wheat loaves = 4 × $ 4 = $16

Cost of the basket – cost of 4 Wheat loaves

= $25 – $16

= $9

Remaining Amount = $9

Cost of 3 Cinnamon Buns = 3 × $2 = $6

Remaining Amount – Cost of 3 Cinnamon Buns

= $9 – $6

= $3

Remaining Amount

Cost of 3 Muffins =3 × $1 = $3

Remaining Amount – Cost of 3 Muffins

= $3 – $3

= $0

The gift basket worth of $25 have 4 Wheat loaves , 3 Cinnamon Buns , 3 Muffins.

Number of 2 in tile he have = 5 tiles

Number of 3 in tile he have = 7 tiles

Number of 4 in tile he have = 6 tiles

To make the tile pattern he wants to use more than one of each length of tile in his pattern.

if we use 1 of each tile

length of all types of tiles = 2 inch + 3 inch + 4 inch = 9 inch

Total length of tile pattern = 30 inches

= 30 inches – 9 inches = 21 inches.

Now,

To make more 21 inches

2 time length of all tiles = 2 × 9 = 18 inches

= 18 inches +3 inch

= 21 inches

Total types of tiles needed for the 30 inch tile pattern = Three 4 in tiles + Four 3 inch tile + Three 2 inch tiles

=Three 4 in tiles + Four 3 inch tile + Three 2 inch tiles

=( 3 × 4) + (4 ×3) + (2 × 3)

= 12 + 12 + 6

= 30 inches.

**Problem Solving**

Performance Task

Picture Planning

Marta has $50 to spend on sketches. She wants to display them in an array of 3 rows, with 4 sketches in each row. Marta wants to include each type of sketch at least two times in her array.

Question 5.

**Reasoning** How many sketches does Marta want?

Answer:

Marta wants a array of 3 rows.

Each row has 4 sketches in each row.

Number of sketches in the array = 3 × 4 = 12 sketches.

Marta wants 12 sketches.

Question 6.

Make Sense and Persevere What is a good plan for solving the problem?

Answer:

As Marta need 12 sketches. and she has $50 to spend on sketches.

There are three types of sketches and their cost

Portrait = $10 each

Animals = $4 each

Landscape =$2 each

She want each type at least two times in the array.

Calculating the cost of each sketches and plan the sketches in the array.

Question 7.

**Be Precise** Show one way Marta can buy sketches to make the array. Use math words and symbols to explain.

Be precise when analyzing the symbols, words, and numbers displayed in a picture graph.

Answer:

As Marta need 12 sketches.

At least 2 sketches of each type in the array

2 Portrait sketches = 2 × $10 = $20

2 Animal sketches = 2 × $4 = $8

2 Landscape sketches = 2 × $2 = $4

Total number of sketches = 2 + 2 + 2 = 6

6 more sketches remaining.

Adding all the costs

= $20 + $8 + $4 = $32

Total amount Marta has = $50

$50 – $32 = $18 remaining.

$18 remaining for 6 more sketches

we can add

=3 Animal sketch + 3 Landscape sketches

$18 = (3 × $4) + (3 × $2)

$18 = $12 + $6

$18 = $18.

Total number of sketches in the Marta’s array = 2 Portrait + 5 Animal + 5 Landscape

=(2 × $10) + (5 × $4) + (5 × $2 )

=$20 + $20 + $10

=$50.

Question 8.

Generalize Suppose Marta wants to make an array of 4 rows, with 3 sketches in each row. Would your answer still work? Explain.

Answer:

If Marta wants to make a array of 4 rows and 3 sketches in each row.

Total sketches = 4 × 3 = 12 sketches.

In both the cases the total sketches are same. So, the answer will work in this case as well.

Just the order of sketches changes.

Jackie has $50 to spend on books. She has made a bar graph to show the number of each type of book the store has in stock. Jackie wants to buy at least 2 of each type of book. Show one way Jackie can spend $50 on books.

Action books cost $5.

Biographies cost $10.

Mysteries cost $5.

Question 1.

What given information will you use to solve the problem?

Answer:

From the bar graph we know

Types of books and the number of books.

Cost of each type of books in the store.

Total amount Jackie can spend on books = $50.

Question 2.

Show one way Jackie can spend $50 on books. Use math words and symbols to explain your thinking.

Answer:

Action books cost $5.

Biographies cost $10.

Mysteries cost $5.

Number of Action books = 4

Number of Mystery books = 5

Number of Biography books = 7

Total money Jackie have = $50

Given that Jackie wants to buy at least 2 of each type of book.

cost of 2 action books = 2 × $5 = $10

$50 – $10 = $40

Remaining money =$40

Cost of 2 Mystery books = 2 × $5 = $10

$40 – $10 = $30

Cost of 2 Biography books = 2 × $10 = $20

$30 – $20 = $10

Remaining money after buys 2 books of each type = $10.

Here are two probabilities

Jackie may buy 2 Action books or 2 Mystery books or 1 Action and 1 mystery book or 1 Biography book.

Here are the ways Jackie spend her $50 buying books.

4 Action books + 2 Mystery books + 2 Biography books = 20 + 10 + 20 = 50

2 Action books + 4 Mystery books + 2 Biography books = 10 + 20 + 20 = 50

3 Action books + 3 Mystery books + 2 Biography books = 15 + 15 + 20 = 50

2 Action books + 2 Mystery books + 3 Biography books = 10 + 10 + 30 = 50
