Sabrina spent ¹₄ of her salary on a blender and ²₅ of the remainder on a vacuum cleaner. If she saved the remaining $216, how much was her salary?
Fraction of the salary spent on the blender = ¹₄

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

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

Blender	Remainder		Total
1x5	3x5		4x5
	Vacuum Cleaner	Savings
	2x3	3x3
5 u	6 u	9 u	20 u

The remainder and the total amount on the vacuum cleaner and the savings are the same. Make the remainder and the total amount on the vacuum cleaner and the savings the same.  LCM of 3 and 5 is 15.

Total salary = 20 u

Amount spent of the blender = 5 u
Amount spent on the vacuum cleaner = 6 u
Amount of savings = 9 u

9 u = 216

1 u = 216 ÷ 9 = 24

Sabrina's salary
= 20 u
= 20 x 24
= $480

Answer(s): $480
