Question

An item is regularly priced at $70. Keiko bought it on sale for 80% off the regular price. How much did Keiko pay? $

Answer 1

Answer:

$14

Step-by-step explanation:

80% of $70 is $14, saving him $56

Answer 2

The other person has a great answer. Here's another approach.

If the discount is 80%, then you have to pay the remaining 20% (the two percentages add to 100%)

20% of 70 = 0.20*70 = 14

The sale price is $14 which is the amount Keiko pays

We see that Keiko saves 70-14 = 56 dollars.
