Answer: $438
To 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 [tex] \frac{361.35}{1} * \frac{82.5}{100} [/tex], and multiplying [tex]361.35 * 100[/tex] and [tex]82.5 * 1[/tex]. The result was [tex] \frac{36135}{82.5}[/tex]. This becomes $438. There is no rounding needed to be done.
