Winnie spent ¹₇ of her salary on a toaster oven and ²₅ of the remainder on a refrigerator. If she saved the remaining $450, how much was her salary?
Fraction of the salary spent on the toaster oven = ¹₇

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

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

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

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

Total salary = 35 u

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

18 u = 450

1 u = 450 ÷ 18 = 25

Winnie's salary
= 35 u
= 35 x 25
= $875

Answer(s): $875
