Question

Help please its important

Answer 1

1. D
2. B
3. Yes

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 2

9514 1404 393

Answer:

1. d. 4x +32y ≤ 224

2. b. x ≤ 24

3. yes

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.
