Ivory spent ¹₇ of her salary on a stand mixer and ²₅ of the remainder on a gas stove. If she saved the remaining $396, how much was her salary?
Fraction of the salary spent on the stand mixer = ¹₇

Fraction of the salary on the remainder
= 1 - ¹₇
= ⁶₇

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

Stand Mixer	Remainder		Total
1x5	6x5		7x5
	Gas Stove	Savings
	2x6	3x6
5 u	12 u	18 u	35 u

The remainder and the total amount on the gas stove and the savings are the same. Make the remainder and the total amount on the gas stove and the savings the same.  LCM of 6 and 5 is 30.

Total salary = 35 u

Amount spent of the stand mixer = 5 u
Amount spent on the gas stove = 12 u
Amount of savings = 18 u

18 u = 396

1 u = 396 ÷ 18 = 22

Ivory's salary
= 35 u
= 35 x 22
= $770

Answer(s): $770
