Linda spent ²₃ of her salary on a speaker and ³₅ of the remainder on a food processor. If she saved the remaining $66, how much was her salary?
Fraction of the salary spent on the speaker = ²₃

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

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

Speaker	Remainder		Total
2x5	1x5		3x5
	Food Processor	Savings
	3x1	2x1
10 u	3 u	2 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 1 and 5 is 5.

Total salary = 15 u

Amount spent of the speaker = 10 u
Amount spent on the food processor = 3 u
Amount of savings = 2 u

2 u = 66

1 u = 66 ÷ 2 = 33

Linda's salary
= 15 u
= 15 x 33
= $495

Answer(s): $495
