Rachel spent ³₅ of her salary on a juicer and ³₅ of the remainder on a vacuum cleaner. If she saved the remaining $136, how much was her salary?
Fraction of the salary spent on the juicer = ³₅

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

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

Juicer	Remainder		Total
3x5	2x5		5x5
	Vacuum Cleaner	Savings
	3x2	2x2
15 u	6 u	4 u	25 u

The remainder and the total amount on the vacuum cleaner and the savings are the same. Make the remainder and the total amount on the vacuum cleaner and the savings the same.  LCM of 2 and 5 is 10.

Total salary = 25 u

Amount spent of the juicer = 15 u
Amount spent on the vacuum cleaner = 6 u
Amount of savings = 4 u

4 u = 136

1 u = 136 ÷ 4 = 34

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

Answer(s): $850
