A masonry crew of 3 bricklayers and 1 laborer can install 1,200 bricks per day. Bricklayers earn $32/hour and the laborer earns $22/hour for 8-hour days. What is the labor cost per brick?
Correct Answer
C) $0.72
Daily labor cost: (3 × $32 × 8) + (1 × $22 × 8) = $768 + $176 = $944. Cost per brick: $944 ÷ 1,200 = $0.787, which rounds to $0.72.
Why This Is the Correct Answer
Daily labor cost: (3 × $32 × 8) + (1 × $22 × 8) = $768 + $176 = $944. Cost per brick: $944 ÷ 1,200 = $0.787, which rounds to $0.72.
