Question

A calculator costs $85 at staples if the calculator is 20% off how much do you pay?

Answer 1

you should get $68 bc when you take 20% off of 100 you are paying 80% and that in a decimal is 0.8 so you multiply 85 by 0.8

Answer 2

$ 17 off

Explanation:

20% is one fifth of the price

So divide 85 by 5 you get 17

Since you only get one 1/5 of the price off you save $17

Just to check and make sure you can do 17 * 5 = 85
