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 sandwich maker = 7 u - 5 u = 2 u
Amount spent on the laptop = 40 u - 5 u - 2 u = 33 u
33 u = 1650
1 u = 1650 ÷ 33 = 50
Her salary
= 40 u
= 40 x 50
= $2000
Answer(s): $2000
