Yen spent ²₅ of her salary on a gas stove and ²₅ of the remainder on a stand mixer. If she saved the remaining $198, how much was her salary?
Fraction of the salary spent on the gas stove = ²₅

Fraction of the salary on the remainder
= 1 - ²₅
= ³₅

Fraction of the remainder on savings
= 1 - ²₅
= ³₅

Gas Stove	Remainder		Total
2x5	3x5		5x5
	Stand Mixer	Savings
	2x3	3x3
10 u	6 u	9 u	25 u

The remainder and the total amount on the stand mixer and the savings are the same. Make the remainder and the total amount on the stand mixer and the savings the same.  LCM of 3 and 5 is 15.

Total salary = 25 u

Amount spent of the gas stove = 10 u
Amount spent on the stand mixer = 6 u
Amount of savings = 9 u

9 u = 198

1 u = 198 ÷ 9 = 22

Yen's salary
= 25 u
= 25 x 22
= $550

Answer(s): $550
