15 of her salary on a toaster oven and

Fraction of the salary spent on the toaster oven =
15 Fraction of the salary on the remainder
= 1 -
15 =
45 Fraction of the remainder on savings
= 1 -

The remainder and the total amount on the lamp and the savings are the same. Make the remainder and the total amount on the lamp and the savings the same. LCM of 4 and 5 is 20.
Total salary = 25 u
Amount spent of the toaster oven = 5 u
Amount spent on the lamp = 12 u
Amount of savings = 8 u
8 u = 232
1 u = 232 ÷ 8 = 29
Nicole's salary
= 25 u
= 25 x 29
= $725
Answer(s): $725
