Next time, Shay, please include the instructions. I'm assuming that our job here is to determine the largest # of boxes of darts that can be purchased.
Shirt cost + x(box of darts cost) = Initial amount
$56 + x($6/box) = $80
Then 56 + 6x = 80, or 6x= 24, or x = 4. He can buy 4 boxes of darts.
The inverse function of the given function is 
<h3>What is the inverse of a function?</h3>
A function g is the inverse of a function f, if and only if the values of y= f(x), x = g(y).
From the formula given:

Let's substitute x with y;


Solve for y;

Add all the sides together
7.2+14.8+16.1+18 = 56.1
The total number of cars rented for the first 5 months is
8 + 16 + 32 + 64 + 128 = 248
They are both the same. There are 60 seconds in one minute, so 60*3 is 180. Since 180=180, they are equal.
