the answer would be $45.55
<3
Step-by-step explanation:
20$ + $50.00 = $70
$70 - $6.95 = $64.5
$64.5 - $9.95 = $54.55
$54.55 - $20 = $34.55
$34.55 + $15 = $49.55
$49.55 - $4 = $45.55
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
