Answer:
Per hour wages must be less than $20 per hour
Explanation:
Given:
Total hour to make a cabinet = 20 hours
Sale price of cabinet = $500
Computation:
Assume
Per hour wages = X
Total amount paid to woodworker = Total hour to make a cabinet × Per hour wages
Total amount paid to woodworker = 20 × X
Total amount paid to woodworker = 20X
Inequality , for at least save $100
500 - 20X ≥ 100
Solution:
-20X ≤ -400
20X ≤ 400
X ≤ 20
Per hour wages must be less than $20 per hour
