If the original price of a pair of shoes is $80 but a sign above the shoes reads “sale - 20% discount”, then what price would a costumer pay for the shoes (excluding tax)?
a.) 64
b.) 6
c.) 16
d.) 80
e.) 60

A.) 64

Step-by-step explanation:

The first step is identifiying the original price of the shoes and the discount

Next you will decide what type of equation you will need. For this situation, you would need a subraction equation.

80 - 20% = ?

If you choose to slove with a calculator, don't put 0.2 in the place of 20%. We dont do this because it will result in a different answer. 80 - 0.2 = 79.8.

Now we solve the problem

80 - 20% = 64

7 is the median   7.875 is the mean
