Answer:

  1. D
  2. B
  3. Yes

Step-by-step explanation:

x: cupcakes

y: cakes

  1. no more than 224 minutes: ≤ 224, average 4 minutes cupcakes: 4x and average 32 minutes cakes: 32y
  2. when you plug in the 4 cakes as y it becomes x≤24....4x+32(4)≤224...(4x+128≤224)-128....(4x≤96)/4...x≤24
  3. when you plug in the given numbers it is a true statement.... 4(32)+32(3)≤224...128+96≤224....224≤224

Answer:

  1.  d. 4x +32y ≤ 224

  2.  b. x ≤ 24

  3.  yes

Step-by-step explanation:

1. For x number of cupcakes, at 4 minutes each, the time required for their decoration is 4x.

For y number of cakes, at 32 minutes each, the time required for their decoration is 32y.

The total decorating time must be less than or equal to 224 minutes:

  4x +32y ≤ 224

__

2. For y=4, the constraint on x is ...

  4x +32(4) ≤ 224

  4x ≤ 96

  x ≤ 24

__

3. We can try the numbers and see if the inequality is true:

  4(32) +32(3) ≤ 224

  128 +96 ≤ 224 . . . . . . . . true (equal)

Yes, it is possible.
