Answer:

First one: x = 3, and y = 2

Second: 5

Third: Yes because he will have $37.50

Fourth: The numbers 2.5 and 3 will make it true

Step-by-step explanation:

1. 4(3) + 2(2) + 3 = 12 + 4 + 3 = 19

2. 4x + 2 = 22, 4x = 20, x = 5

3. 2.25y + 7.25z + 11.25, 2.25(2) + 7.25(3) + 11.25 = 4.5 + 21.75 + 11.25 = 37.5

He will get $37.50, which is enough.

4. The numbers 2.5 and 3 will make it true: 2(2.5) + 3 = 5 + 3 = 8, 2(3) + 3 = 6 + 3 = 9, the numbers below it won't make it true.
