Vanessa spent ¹₈ of her salary on a washing machine and ³₄ of the remainder on a blender. If she saved the remaining $245, how much was her salary?
Fraction of the salary spent on the washing machine = ¹₈

Fraction of the salary on the remainder
= 1 - ¹₈
= ⁷₈

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

Washing Machine	Remainder		Total
1x4	7x4		8x4
	Blender	Savings
	3x7	1x7
4 u	21 u	7 u	32 u

The remainder and the total amount on the blender and the savings are the same. Make the remainder and the total amount on the blender and the savings the same.  LCM of 7 and 4 is 28.

Total salary = 32 u

Amount spent of the washing machine = 4 u
Amount spent on the blender = 21 u
Amount of savings = 7 u

7 u = 245

1 u = 245 ÷ 7 = 35

Vanessa's salary
= 32 u
= 32 x 35
= $1120

Answer(s): $1120
