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 muffin maker = 7 u - 4 u = 3 u
Amount spent on the laptop = 24 u - 4 u - 3 u = 17 u
17 u = 680
1 u = 680 ÷ 17 = 40
Her salary
= 24 u
= 24 x 40
= $960
