Fraction of the remaining salary left

25 =
35 35 of the remaining salary =
16 of the total salary
3x15x1 of the remaining salary =
1x36x3 of the total salary
35 of the remaining salary =
318 of the total salary
Total salary = 18 u
Amount left = 3 u
Amount spent on the water heater = 5 u - 3 u = 2 u
Amount spent on the washing machine = 18 u - 3 u - 2 u = 13 u
13 u = 390
1 u = 390 ÷ 13 = 30
Her salary
= 18 u
= 18 x 30
= $540
Answer(s): $540
