Step-by-step explanation:
Replace f(x) with y
Y = 2x -5
Swap roles of x
X= 2y-5
5+x =2y

5+x /2 = y
Replace y with inverse f^-1(x)
Answer= f^-1(x) = 5+x / 2

A.
A = 100 + 0.15*s
B = 150 + 0.10*s
b.
100+0.15*s < 150+0.10*s
0.15*s < 50+0.10*s
0.05*s < 50
s < 1000
Thus any weekly sales less than $1,000, and plan B would be better.
