f = (f1 f2) / (f1 + f2)

f(f1 + f2) = f1 f2

f f 1 + f f 2 = f1 f 2

f1 f2 - f f2 = f f1

f2 (f1 - f) = f f1

f2 = (f f1) / (f1 - f) <==== solution

You charge customers $18.75 for lube service, parts, and labor. Assuming you take one hour's labor at $15, and the parts cost $3

hram777 [196]

Let
T---------> <span>the tax rate on the parts in $

we know that
$18.75=$15+$3.50+$T
T=18.75-15-3.5
T=$0.25
so
$3.50----------> 100%
$0.25--------> x
x=0.25*100/3.50------> x=7.14%------> x=7.1%

the answer is
7.1%</span>
