18 =
78 78 of the remaining salary =
27 of the total salary
7x28x2 of the remaining salary =
2x77x7 of the total salary
1416 of the remaining salary =
1449 of the total salary
Total salary = 49 u
Amount left = 14 u
Amount spent on the sandwich maker = 16 u - 14 u = 2 u
Amount spent on the portable air-conditioner = 49 u - 14 u - 2 u = 33 u
33 u = 1320
1 u = 1320 ÷ 33 = 40
Her salary
= 49 u
= 49 x 40
= $1960
Answer(s): $1960
