Gillian spent ²₃ of her salary on a television set and ³₅ of the remainder on a stand mixer. If she saved the remaining $80, how much was her salary?
Fraction of the salary spent on the television set = ²₃

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

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

Television Set	Remainder		Total
2x5	1x5		3x5
	Stand Mixer	Savings
	3x1	2x1
10 u	3 u	2 u	15 u

The remainder and the total amount on the stand mixer and the savings are the same. Make the remainder and the total amount on the stand mixer and the savings the same.  LCM of 1 and 5 is 5.

Total salary = 15 u

Amount spent of the television set = 10 u
Amount spent on the stand mixer = 3 u
Amount of savings = 2 u

2 u = 80

1 u = 80 ÷ 2 = 40

Gillian's salary
= 15 u
= 15 x 40
= $600

Answer(s): $600
