Answer:

A.28x+32y

B.199 hours

Step-by-step explanation:

Let carpenters work for  x hours and painters work for y hours.

Nelson must spend money <$7500

Carpenters charge per hour=$28

Painters charge per hour=$32

A.We have to write inequalities which represents this situation

According to question

28x+32y

B.If hires carpenters work  for total time=40 hours

We have to find the maximum number of hours for which painters can work without exceeding the budget.

Substitute the value in above inequality equation then, we get

28(40)+32y

1120+32y

Subtracting 1120 on both sides

32y

32y

Divide by 32 on both sides then we get

y

y

Hence,painters can work for  maximum 199 hours.
