Fraction of the remaining salary left
= 1 -
27 =
57 57 of the remaining salary =
16 of the total salary
5x17x1 of the remaining salary =
1x56x5 of the total salary
57 of the remaining salary =
530 of the total salary
Total salary = 30 u
Amount left = 5 u
Amount spent on the speaker = 7 u - 5 u = 2 u
Amount spent on the laptop = 30 u - 5 u - 2 u = 23 u
23 u = 575
1 u = 575 ÷ 23 = 25
Her salary
= 30 u
= 30 x 25
= $750
Answer(s): $750
