38 =
58 58 of the remaining salary =
17 of the total salary
5x18x1 of the remaining salary =
1x57x5 of the total salary
58 of the remaining salary =
535 of the total salary
Total salary = 35 u
Amount left = 5 u
Amount spent on the speaker = 8 u - 5 u = 3 u
Amount spent on the home theater system = 35 u - 5 u - 3 u = 27 u
27 u = 540
1 u = 540 ÷ 27 = 20
Her salary
= 35 u
= 35 x 20
= $700
Answer(s): $700
