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.
Step-by-step explanation:
sum of all angles in a triangle is 180 degrees
x + 3x + 13 + x - 8 = 180
5x + 5 = 180
5x = 175
x = 37°
A = 3x + 13
3(37) + 13
A = 124°
