Tammy spent ¹₈ of her salary on a refrigerator and ²₅ of the remainder on a stand mixer. If she saved the remaining $714, how much was her salary?
Fraction of the salary spent on the refrigerator = ¹₈

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

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

Refrigerator	Remainder		Total
1x5	7x5		8x5
	Stand Mixer	Savings
	2x7	3x7
5 u	14 u	21 u	40 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 7 and 5 is 35.

Total salary = 40 u

Amount spent of the refrigerator = 5 u
Amount spent on the stand mixer = 14 u
Amount of savings = 21 u

21 u = 714

1 u = 714 ÷ 21 = 34

Tammy's salary
= 40 u
= 40 x 34
= $1360

Answer(s): $1360
