Answer:
A.
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
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
Subtracting 1120 on both sides
Divide by 32 on both sides then we get
Hence,painters can work for maximum 199 hours.
