Answer:
f^-1(x)= 1/3 x
Step-by-step explanation:
y = 3x
To find the inverse, exchange x and y
x = 3y
Solve for y by dividing by 3 on each side
x/3 = 3y/3
1/3x = y
The inverse is 1/3x

Leah has 80 less paychecks than the weekly person.
Leah is getting 24 paychecks in 2 years, Weekly person gets 104 paychecks in 2 years, 104 - 24 = 80 paychecks.
