Xandra spent ¹₈ of her salary on a television set and ³₅ of the remainder on a refrigerator. If she saved the remaining $546, how much was her salary?
Fraction of the salary spent on the television set = ¹₈

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

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

Television Set	Remainder		Total
1x5	7x5		8x5
	Refrigerator	Savings
	3x7	2x7
5 u	21 u	14 u	40 u

The remainder and the total amount on the refrigerator and the savings are the same. Make the remainder and the total amount on the refrigerator and the savings the same.  LCM of 7 and 5 is 35.

Total salary = 40 u

Amount spent of the television set = 5 u
Amount spent on the refrigerator = 21 u
Amount of savings = 14 u

14 u = 546

1 u = 546 ÷ 14 = 39

Xandra's salary
= 40 u
= 40 x 39
= $1560

Answer(s): $1560
