Illinois Roofing Practice Exam

A two-person crew with one person being paid $25 per hour and the other $15 per hour installed 10 squares of material in an 8-hour shift. What was the cost of labor per square?

1. $25 per square

2. $20 per square

3. $35 per square

4. $32 per square

The correct answer is: $32 per square

To determine the cost of labor per square, first calculate the total labor cost for the crew. One worker earns $25 per hour and the other earns $15 per hour. In an 8-hour shift, the first worker's total pay would be: $25/hour × 8 hours = $200 The second worker's total pay would be: $15/hour × 8 hours = $120 Adding both wages gives the total labor cost: $200 + $120 = $320 Next, you need to find the cost of labor per square. Since the crew installed 10 squares of material, you divide the total labor cost by the number of squares: $320 ÷ 10 squares = $32 per square This calculation shows that for each square installed, the labor cost incurred was $32. Thus, the correct answer reflects the accurate labor cost calculation for the work completed.
