Fraction of the remaining salary left
= 1 -
16 =
56 56 of the remaining salary =
37 of the total salary
5x36x3 of the remaining salary =
3x57x5 of the total salary
1518 of the remaining salary =
1535 of the total salary
Total salary = 35 u
Amount left = 15 u
Amount spent on the toaster = 18 u - 15 u = 3 u
Amount spent on the washing machine = 35 u - 15 u - 3 u = 17 u
17 u = 680
1 u = 680 ÷ 17 = 40
Her salary
= 35 u
= 35 x 40
= $1400
Answer(s): $1400
