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

Respuesta :

Answer:

The answer is C.

Step-by-step explanation:

4 x 12 is how much money per worker per hour. 20 x 160 is how much the cost for the concrete. Adding them gets you the total cost.

Hope this helped!

The equation that can be used to describe the contractor’s total cost, C, if the project takes h hours to complete is C = (4 × 12)h + (20 + 160)

Given:

Number of workers = 4

Earnings of each work = $12

Yards of concrete = 20 cubic yards

Cost per cubic yards = $160

let

C = total cost

h = number of hours needed to complete the project

C = (Number of workers + Earnings of each work)number of hours + (Yards of concrete + Cost per cubic yards)

C = (4 Ă— 12)h + (20 + 160)

Therefore, the equation that can be used to describe the contractor’s total cost, C, if the project takes h hours to complete is C = (4 × 12)h + (20 + 160)
