Answer 1

Hello @PrettyEyes !

For this problem the first step is to figure out the price after the discount.

If we are taking 20% OFF
this means we want 80% of the original price

80% as a decimal = 0.8

so what is 40*0.8 = ?

Answer 2

the number you get above would not be your final answer because we would still have to multiply by 1.05

Answer 3

im still confused

Answer 4

what is 40 x 0.8 = ?

Answer 5

32

Answer 6

awesome $32 is the price after the discount


now we want to consider the price after the tax. If the tax = 5%
5% = 0.05 converted to a decimal

The price after tax will be:
32 x 1.05

Answer 7

33.6

Answer 8

that would be your answer! :)
