37 =
47 47 of the remaining salary =
19 of the total salary
4x17x1 of the remaining salary =
1x49x4 of the total salary
47 of the remaining salary =
436 of the total salary
Total salary = 36 u
Amount left = 4 u
Amount spent on the deep fryer = 7 u - 4 u = 3 u
Amount spent on the home theater system = 36 u - 4 u - 3 u = 29 u
29 u = 580
1 u = 580 ÷ 29 = 20
Her salary
= 36 u
= 36 x 20
= $720
Answer(s): $720
