Jade spent ¹₅ of her salary on a washing machine and ²₅ of the remainder on a toaster oven. If she saved the remaining $408, how much was her salary?
Fraction of the salary spent on the washing machine = ¹₅

Fraction of the salary on the remainder
= 1 - ¹₅
= ⁴₅

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

Washing Machine	Remainder		Total
1x5	4x5		5x5
	Toaster Oven	Savings
	2x4	3x4
5 u	8 u	12 u	25 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 4 and 5 is 20.

Total salary = 25 u

Amount spent of the washing machine = 5 u
Amount spent on the toaster oven = 8 u
Amount of savings = 12 u

12 u = 408

1 u = 408 ÷ 12 = 34

Jade's salary
= 25 u
= 25 x 34
= $850

Answer(s): $850
