Which proportion could be used to solve the following problem?
A recipe for sesame chicken calls for
cup of chopped carrots. If the recipe
2
is for 4 servings, how many cups of
carrots are needed for 9 servings?

Cups of carrot needed for 9 servings = 4.5 cups

Step-by-step explanation:

A recipe for sesame chicken calls for cup of chopped carrots

recipe 2 is for 4 servings

That is

2 cups of carrot = 4 servings

2 : 4

= 1 : 2

1 cup of carrot = 2 servings

how many cups of

carrots are needed for 9 servings?

Let x= number of carrot needed for 9 servings

1 : 2 = x : 9

1 /2 = x/ 9

Cross product

1*9 = 2*x

9=2x

Divide both sides by 2

9/2 = x

x= 4.5 Or 4 1/2

B

Step-by-step explanation:

0.10 × 80 = 8

80 - 8 = 72

0.07 × 72 = 5.04

72 + 5.04 = 77.04
