A labor crew for placing concrete consists of one labor foreman at $26.70 per hour, one cement fin­isher at $29.30 per hour, five laborers at $24.45 per hour each, and one equipment operator at $33.95 per hour. Such a crew, called a C20 crew, can place 165 cubic yards of concrete per 8-hour day. Deter­mine (a) the cost per day of labor for the C20 crew, (b) the cost of the C20 crew per cubic yard of con­crete, and (c) the cost to place 550 cubic yards of concrete.

What will be an ideal response?


(a) Crew cost per day = 8[26.70 + 29.30 + 5(24.45) + 33.95] = $1697.60

(b) Cost per cubic yard = 1697.60/165 = $10.29 per cubic yard

(c) Cost for 550 cubic yards = 10.29(550) = $5659
