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 kettle = 7 u - 4 u = 3 u
Amount spent on the portable air-conditioner = 36 u - 4 u - 3 u = 29 u
29 u = 435
1 u = 435 ÷ 29 = 15
Her salary
= 36 u
= 36 x 15
= $540
Answer(s): $540
