Joelle spent ²₅ of her salary on a food processor and ²₅ of the remainder on a refrigerator. If she saved the remaining $234, how much was her salary?
Fraction of the salary spent on the food processor = ²₅

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

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

Food Processor	Remainder		Total
2x5	3x5		5x5
	Refrigerator	Savings
	2x3	3x3
10 u	6 u	9 u	25 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 3 and 5 is 15.

Total salary = 25 u

Amount spent of the food processor = 10 u
Amount spent on the refrigerator = 6 u
Amount of savings = 9 u

9 u = 234

1 u = 234 ÷ 9 = 26

Joelle's salary
= 25 u
= 25 x 26
= $650

Answer(s): $650
