A contractor hires 4 workers for a construction project. Each worker is paid $12 per hour. The contractor also buys 20 cubic yar

ds of concrete for the project, at a price of $160 per cubic yard. Which equation best describes the contractor’s total cost, C, if the project takes h hours to complete?
C = (4 x 12)h + (20 x 160)

C = 4(12 + 160)h + 20

C = (20 x 160)h + (4 x 12)

C = 12h + (20 x 160)
