A repair bill for a car is $648.45. The parts cost $265.95. The labor cost is $85 per hour. Write and solve an equation to find the number of hours of labor spent repairing the car.

Answer :

The repair bill is an illustration of a linear equation. The equation that represents the scenario is: 648.45 = 265.95+85x

And the solution (i.e. number of hours) is: 4.5 hours

A repair bill for a car is $648.45 and the parts cost $265.95 .the Labor cost is $85 per hour

we have to find the number of hours of labor spent repairing the car

Given that:

bill = 648.45 dollar

parts = 265.95 dollar

labor = 85 dollar per hour

Let the number of hours spent be x

So, the equation is:

Bill = parts + labor * x

This gives;

648.45 = 265.95 +85 x

Collect like terms

648.45 - 265.95 =85x

382.5 = 85x

Divide both sides by 85

4.5 = x

x= 4.5

Hence the equation is

648.45 = 265.95 +85 x

And the solution (i.e. number of hours) is: 4.5 hours
