Victoria spent ¹₈ of her salary on a toaster oven and ²₃ of the remainder on a washing machine. If she saved the remaining $273, how much was her salary?
Fraction of the salary spent on the toaster oven = ¹₈

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

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

Toaster Oven	Remainder		Total
1x3	7x3		8x3
	Washing Machine	Savings
	2x7	1x7
3 u	14 u	7 u	24 u

The remainder and the total amount on the washing machine and the savings are the same. Make the remainder and the total amount on the washing machine and the savings the same.  LCM of 7 and 3 is 21.

Total salary = 24 u

Amount spent of the toaster oven = 3 u
Amount spent on the washing machine = 14 u
Amount of savings = 7 u

7 u = 273

1 u = 273 ÷ 7 = 39

Victoria's salary
= 24 u
= 24 x 39
= $936

Answer(s): $936
