Replace x with 3:

f(x) = 20(0.5)^x

f(3) = 20(0.5)^3

First do 0.5^3 = 0.125

Now multiply that by 20:

20 x 0.125 = 2.5


f(3) = 2.5

First you need to make a multiplier:

Then you multiply the price by 1.12 to get the final answer;
22 * 0.78 = 17.16

This means it cost $17.16 after the 12% sales tax.
