57 57 of the remaining salary =
13 of the total salary
5x17x1 of the remaining salary =
1x53x5 of the total salary
57 of the remaining salary =
515 of the total salary
Total salary = 15 u
Amount left = 5 u
Amount spent on the hand blender = 7 u - 5 u = 2 u
Amount spent on the portable air-conditioner = 15 u - 5 u - 2 u = 8 u
8 u = 280
1 u = 280 ÷ 8 = 35
Her salary
= 15 u
= 15 x 35
= $525
Answer(s): $525
