27 =
57 57 of the remaining salary =
18 of the total salary
5x17x1 of the remaining salary =
1x58x5 of the total salary
57 of the remaining salary =
540 of the total salary
Total salary = 40 u
Amount left = 5 u
Amount spent on the water heater = 7 u - 5 u = 2 u
Amount spent on the television = 40 u - 5 u - 2 u = 33 u
33 u = 1320
1 u = 1320 ÷ 33 = 40
Her salary
= 40 u
= 40 x 40
= $1600
