38 =
58 58 of the remaining salary =
15 of the total salary
5x18x1 of the remaining salary =
1x55x5 of the total salary
58 of the remaining salary =
525 of the total salary
Total salary = 25 u
Amount left = 5 u
Amount spent on the speaker = 8 u - 5 u = 3 u
Amount spent on the washing machine = 25 u - 5 u - 3 u = 17 u
17 u = 510
1 u = 510 ÷ 17 = 30
Her salary
= 25 u
= 25 x 30
= $750
