Defined the inverse, inner change the variables and solve for y.
F^-1(x)=x/5-2/5
Answer:
probably 9/2 because its a fraction
Step-by-step explanation:
First, find the decreased price by multiplying 100 by 8% and subtracting:
100 x 0.08 = 8
100-8 = 92 ( reduced price )
now multiply reduced price by 8% and add:
92 x 0.08 = 7.36
92 + 7.36 = $99.36
