Fraction of the remaining salary left
= 1 -
18 =
78 78 of the remaining salary =
29 of the total salary
7x28x2 of the remaining salary =
2x79x7 of the total salary
1416 of the remaining salary =
1463 of the total salary
Total salary = 63 u
Amount left = 14 u
Amount spent on the toaster = 16 u - 14 u = 2 u
Amount spent on the notebook = 63 u - 14 u - 2 u = 47 u
47 u = 940
1 u = 940 ÷ 47 = 20
Her salary
= 63 u
= 63 x 20
= $1260
Answer(s): $1260
