Answer: $18.19
Step-by-step explanation:
The tax is applied after the discount so first find the discounted price:
= Price * ( 1 - discount rate)
= 20 * ( 1 - 15%)

The inverse of the given function is y = (12-x)/6
<h3>Inverse of a function</h3>
Given the following function expressed as:
f(x) = -6x +1/2
Replace y with x
x = -6y + 1/2
Make y the subject of the formula
6y = -x + 12
y = (12-x)/6
Hence the inverse of the given function is y = (12-x)/6
