Tammy spent ¹₇ of her salary on a speaker and ²₅ of the remainder on a toaster oven. If she saved the remaining $612, how much was her salary?
Fraction of the salary spent on the speaker = ¹₇

Fraction of the salary on the remainder
= 1 - ¹₇
= ⁶₇

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

Speaker	Remainder		Total
1x5	6x5		7x5
	Toaster Oven	Savings
	2x6	3x6
5 u	12 u	18 u	35 u

The remainder and the total amount on the toaster oven and the savings are the same. Make the remainder and the total amount on the toaster oven and the savings the same.  LCM of 6 and 5 is 30.

Total salary = 35 u

Amount spent of the speaker = 5 u
Amount spent on the toaster oven = 12 u
Amount of savings = 18 u

18 u = 612

1 u = 612 ÷ 18 = 34

Tammy's salary
= 35 u
= 35 x 34
= $1190

Answer(s): $1190
