Answer:
43.20
Step-by-step explanation:
First we need to find the sales tax
tax = price * tax rate
tax = 40 * 8%
= 40*.08
=3.2
We final cost is the price plus the sales tax
final cost = price + tax
= 40+3.2
= 43.20
The inverse function is
H-1(x)=3=x
The expanded form would be 100.000 +20.000+0.000+.500+.070+.001
