The equation is 365 + 66x = 1487 and the number of labor hours was 17

Write an equation you can use to answer this question.

The given parameters are:

Total charges = 1487

Parts = 365

Hourly rate = 66

Let the number of hours be x.

So, we have the following equation

Parts + Hourly rate * x = Total charges

Substitute the known values in the above equation

365 + 66x = 1487

Hence, the equation is 365 + 66x = 1487

Solve your equation in part (A) to find the number of labor hours needed to do the job.

In (a), we have:

365 + 66x = 1487

Subtract 365 from both sides

66x = 1122

Divide both sides by 66

x = 17

Hence, the number of labor hours was 17
