Eva spent ¹₇ of her salary on a microwave oven and ³₅ of the remainder on a toaster oven. If she saved the remaining $336, 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 - ³₅
= ²₅

Microwave Oven	Remainder		Total
1x5	6x5		7x5
	Toaster Oven	Savings
	3x6	2x6
5 u	18 u	12 u	35 u

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

Total salary = 35 u

Amount spent of the microwave oven = 5 u
Amount spent on the toaster oven = 18 u
Amount of savings = 12 u

12 u = 336

1 u = 336 ÷ 12 = 28

Eva's salary
= 35 u
= 35 x 28
= $980

Answer(s): $980
