Question

Margo saved $250 on a computer that was marked as 20% off. What did she pay for the computer?

Answer 1

The answer is $1000.

EXPLANATION

Firstly, we know that $250 is 20% of the original cost. Because of this we multiply $250 by 5, to get 100%=$1250.

Because she saved $250, we take this away from $1250, to get a final answer  of $1000.

Answer 2

I think you need to subtract 250-20=230. So Margo payed $230 for the computer. Hope this helps.
