Question

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

Answer 1

Answer:

8 dollars

Step-by-step explanation:

20/100 = x/10

100x=20

x=2

You save two dollars

10-2 = 8

$8

Answer 2

1 : Turn 20% into a decimal.

20% as a decimal would be: 0.20.  Or .20.

2 : Take 10 and times it by 0.20.  

10 x 0.20 = 2

3 : Take 10 and subtract it by the last answer- 2.

10 - 2 = 8

4 :  Put the dollar sign on you answer so we know it's in money.

= $8

And we're done!
