Kylie spent ¹₅ of her salary on a toaster oven and ²₃ of the remainder on a food processor. If she saved the remaining $136, how much was her salary?
Fraction of the salary spent on the toaster oven = ¹₅

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

Fraction of the remainder on savings
= 1 - ²₃
= ¹₃

Toaster Oven	Remainder		Total
1x3	4x3		5x3
	Food Processor	Savings
	2x4	1x4
3 u	8 u	4 u	15 u

The remainder and the total amount on the food processor and the savings are the same. Make the remainder and the total amount on the food processor and the savings the same.  LCM of 4 and 3 is 12.

Total salary = 15 u

Amount spent of the toaster oven = 3 u
Amount spent on the food processor = 8 u
Amount of savings = 4 u

4 u = 136

1 u = 136 ÷ 4 = 34

Kylie's salary
= 15 u
= 15 x 34
= $510

Answer(s): $510
