38 =
58 58 of the remaining salary =
16 of the total salary
5x18x1 of the remaining salary =
1x56x5 of the total salary
58 of the remaining salary =
530 of the total salary
Total salary = 30 u
Amount left = 5 u
Amount spent on the sandwich maker = 8 u - 5 u = 3 u
Amount spent on the portable air-conditioner = 30 u - 5 u - 3 u = 22 u
22 u = 880
1 u = 880 ÷ 22 = 40
Her salary
= 30 u
= 30 x 40
= $1200
Answer(s): $1200
