Question

You decide to get an estimate on the cost of repairs for the green food truck

The mechanic explains that the cost of the repairs comes out to be about
$9,500. This price includes the cost of labor and the cost of the parts needed
to do the repairs. If labor costs are 3/5 the cost of the parts, how much
would you save by doing the repairs yourself and just purchasing the parts?

Answer 1

$3562.50

Explanation:

If the cost ratio is ...

labor : parts = 3/5 : 1 = 3 : 5

then the ratio of labor to the whole cost is ...

labor : total = 3 : (3+5) = 3 : 8

The amount saved by not paying for labor is ...

(3/8) × $9500 = $3562.50 . . . labor charge
