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)

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 × 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)

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!

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8
