Answer:
$5.38
Step-by-step explanation:
$13.45 / 5 (To find the value of 1 pound of cheese, Total money spent divided by total pound of cheese bought)
$2.69 (1 pound of cheese will cost)
So, $2.69 x 2 (Multiply by 2 to find how much 2 pound of cheese will cost)
$5.38

it means that x has now to be the result variable, and y the input variable.
so,
y = 3x - 5
y + 5 = 3x
x = (y + 5)/3
and as a final touch, to make the inverse a "normal function", we rename x to y and y to x and get
y = (x + 5)/3
as the inverse function
