Wendy spent ¹₇ of her salary on a microwave oven and ³₄ of the remainder on a gas stove. If she saved the remaining $93, how much was her salary?
Fraction of the salary spent on the microwave oven = ¹₇

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

Fraction of the remainder on savings
= 1 - ³₄
= ¹₄

Microwave Oven	Remainder		Total
1x2	6x2		7x2
	Gas Stove	Savings
	3x3	1x3
2 u	9 u	3 u	14 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 4 is 12.

Total salary = 14 u

Amount spent of the microwave oven = 2 u
Amount spent on the gas stove = 9 u
Amount of savings = 3 u

3 u = 93

1 u = 93 ÷ 3 = 31

Wendy's salary
= 14 u
= 14 x 31
= $434

Answer(s): $434
