37 =
47 47 of the remaining salary =
15 of the total salary
4x17x1 of the remaining salary =
1x45x4 of the total salary
47 of the remaining salary =
420 of the total salary
Total salary = 20 u
Amount left = 4 u
Amount spent on the deep fryer = 7 u - 4 u = 3 u
Amount spent on the notebook = 20 u - 4 u - 3 u = 13 u
13 u = 520
1 u = 520 ÷ 13 = 40
Her salary
= 20 u
= 20 x 40
= $800
