Answer: $438To solve this equation, you cross multiply. I first subtracted 17.5 from 100 in order to get the percentage value that $361.35 was of its original price. Since 100 - 17.5 = 82.5, the washing machine is 82.5% of its original price.
I cross multiplied by writing

, and multiplying

and

. The result was

. This becomes $438. There is no rounding needed to be done.
3250 / 625 = 5.2
