Joelle spent ¹₄ of her salary on a food processor and ³₄ of the remainder on a juicer. If she saved the remaining $72, how much was her salary?
Fraction of the salary spent on the food processor = ¹₄

Fraction of the salary on the remainder
= 1 - ¹₄
= ³₄

Fraction of the remainder on savings
= 1 - ³₄
= ¹₄

Food Processor	Remainder		Total
1x4	3x4		4x4
	Juicer	Savings
	3x3	1x3
4 u	9 u	3 u	16 u

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

Total salary = 16 u

Amount spent of the food processor = 4 u
Amount spent on the juicer = 9 u
Amount of savings = 3 u

3 u = 72

1 u = 72 ÷ 3 = 24

Joelle's salary
= 16 u
= 16 x 24
= $384

Answer(s): $384
