Esther spent ¹₄ of her salary on a juicer and ³₅ of the remainder on a stand mixer. If she saved the remaining $150, how much was her salary?
Fraction of the salary spent on the juicer = ¹₄

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

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

Juicer	Remainder		Total
1x5	3x5		4x5
	Stand Mixer	Savings
	3x3	2x3
5 u	9 u	6 u	20 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 3 and 5 is 15.

Total salary = 20 u

Amount spent of the juicer = 5 u
Amount spent on the stand mixer = 9 u
Amount of savings = 6 u

6 u = 150

1 u = 150 ÷ 6 = 25

Esther's salary
= 20 u
= 20 x 25
= $500

Answer(s): $500
