Fraction of the remaining salary left

18 =
78 78 of the remaining salary =
29 of the total salary
7x28x2 of the remaining salary =
2x79x7 of the total salary
1416 of the remaining salary =
1463 of the total salary
Total salary = 63 u
Amount left = 14 u
Amount spent on the sandwich maker = 16 u - 14 u = 2 u
Amount spent on the home theater system = 63 u - 14 u - 2 u = 47 u
47 u = 1880
1 u = 1880 ÷ 47 = 40
Her salary
= 63 u
= 63 x 40
= $2520
Answer(s): $2520
