Fraction of the remaining salary left
= 1 -
27 =
57 57 of the remaining salary =
19 of the total salary
5x17x1 of the remaining salary =
1x59x5 of the total salary
57 of the remaining salary =
545 of the total salary
Total salary = 45 u
Amount left = 5 u
Amount spent on the lamp = 7 u - 5 u = 2 u
Amount spent on the refrigerator = 45 u - 5 u - 2 u = 38 u
38 u = 570
1 u = 570 ÷ 38 = 15
Her salary
= 45 u
= 45 x 15
= $675
Answer(s): $675
