Question 3.
Jasmine is making cookies for the fourth grade class. The recipe calls for 8 ounces of chocolate chips. She needs to triple the recipe to have enough for everyone, and she is going to add 2 more ounces of chocolate chips to the tripled batch to make the cookies extra delicious. How many ounces of chocolate chips does she need?

a. Use numbers, labeled sketches, or words to solve the problem. Show your work.
Answer:
Given,
Jasmine is making cookies for the fourth grade class. The recipe calls for 8 ounces of chocolate chips.
8 × 3 = 24
She needs to triple the recipe to have enough for everyone, and she is going to add 2 more ounces of chocolate chips to the tripled batch to make the cookies extra delicious.
24 + 2 = 26

b. Fill in the bubble beside the equation that best represents this problem. (The letter c stands for ounces of chocolate chips.)
Bridges in Mathematics Grade 4 Home Connections Unit 2 Module 1 Answer Key 10 8 + 3 + 2 = c
Bridges in Mathematics Grade 4 Home Connections Unit 2 Module 1 Answer Key 10 (8 × 3) + 2 = c
Bridges in Mathematics Grade 4 Home Connections Unit 2 Module 1 Answer Key 10 (8 × 3) – 2 = c
Answer:
(8 × 3) + 2 = c
c = 24 + 2
c = 26
Option B is the correct answer.

Question 4.
Jasmine can fit 12 cookies on a cookie sheet. She needs 6 times that many cookies for the whole fourth grade. Jasmine also wants to have 2 cookies for each of the 4 teachers. How many cookies does Jasmine need to make? Show your work.
Answer:
Given,
Jasmine can fit 12 cookies on a cookie sheet. She needs 6 times that many cookies for the whole fourth grade.
12 × 6 = 72
Jasmine also wants to have 2 cookies for each of the 4 teachers.
4 × 2 = 8
72 + 8 = 80

Question 5.
CHALLENGE When 2 pieces of rope are placed end-to-end, they measure 40 meters in length. When the 2 pieces are laid side-by-side, one is 10 meters longer than the other. How long is each piece of rope? Show your work.
Answer:
Given,
When 2 pieces of rope are placed end-to-end, they measure 40 meters in length.
a + b = 40 —(1)
When the 2 pieces are laid side-by-side, one is 10 meters longer than the other.
a = b + 10 —(2)
a + b = 40
(b + 10) + b = 40
b + b + 10 = 40
2b + 10 = 40
2b = 40 – 10
2b = 30
b = 30/2
b = 15

a = b + 10
a = 15 + 10
a = 25
Thus the length of each rope will be 15 and 25 meters.

Question 3.
CHALLENGE Dana has only nickels in her hand, and Ajah has exactly the same number of dimes and no other coins. Together they have a total of 90⊄. How many coins is each person holding? Show your work below.
Answer:
Given,
Dana has only nickels in her hand, and Ajah has exactly the same number of dimes and no other coins. Together they have a total of 90⊄.
A nickel is worth $0.05
Dana has 0.05x
A dime is worth $0.1
Ajah has 0.1c
0.05x + 0.1x = 0.9
0.15x = 0.9
x = 0.9/0.15
x = 6
Each person is holding 6 coins.
