Answer:
You will pay $65.88 in total
Step-by-step explanation:
Bill amount: $54
Tip: 22% = $54 * 0.22 = $11.88
Sum up: $54 + $11.88 = $65.88
f(x) = 6x
To find the inverse, replace f(x) with Y:
y = 6x
Now switch the variables:
x = 6y
Solve for Y by dividing both sides by 6:
y = x/6
Now replace y with f^-1 (x):
f^-1 (x) = x/6
