Question

Andrew paid $10 for a burger. The burger went on sale and there was a discount of 20%. what was the sale price of the burgers?

Answer 1

The sales price is $8. This is because 10=100 and if you were to do 20/100 that's would also be 2. Therefore if you do 10-2 you would get 8.

Answer 2

20% = .20
10 times .20 = 2
10-2= 8
$8
