The regular price for an item that is on sale for $38.40 is $48.
A function takes in values, applies specific operations to them, and produces an output. The inverse function acts, agrees with the outcome, and returns to the initial function.
The output of a function is returned by the inverse function, which also returns the initial value.
Given the sale price of an item that has a regular price of R is,
S = R - 0.2R
the inverse function of R is
S = R(1 - 0.2)
S = R(0.8)
R = S/0.8
and the sale price is $38.40
regular price is,
R = S/0.8
R = 38.40/0.8
R = $48.
Hence the regular price is $48.

Answer:
R=48
Step-by-step explanation:
S=R(1-0.2) R = 38.40/.8
S=R(.8) R = 48
R=5/.8
