37 =
47 47 of the remaining salary =
16 of the total salary
4x17x1 of the remaining salary =
1x46x4 of the total salary
47 of the remaining salary =
424 of the total salary
Total salary = 24 u
Amount left = 4 u
Amount spent on the deep fryer = 7 u - 4 u = 3 u
Amount spent on the portable air-conditioner = 24 u - 4 u - 3 u = 17 u
17 u = 340
1 u = 340 ÷ 17 = 20
Her salary
= 24 u
= 24 x 20
= $480
Answer(s): $480
