Fraction of the remaining salary left
= 1 -
18 =
78 78 of the remaining salary =
37 of the total salary
7x38x3 of the remaining salary =
3x77x7 of the total salary
2124 of the remaining salary =
2149 of the total salary
Total salary = 49 u
Amount left = 21 u
Amount spent on the deep fryer = 24 u - 21 u = 3 u
Amount spent on the home theater system = 49 u - 21 u - 3 u = 25 u
25 u = 500
1 u = 500 ÷ 25 = 20
Her salary
= 49 u
= 49 x 20
= $980
Answer(s): $980
