Fraction of the remaining salary left
= 1 -
16 =
56 56 of the remaining salary =
25 of the total salary
5x26x2 of the remaining salary =
2x55x5 of the total salary
1012 of the remaining salary =
1025 of the total salary
Total salary = 25 u
Amount left = 10 u
Amount spent on the muffin maker = 12 u - 10 u = 2 u
Amount spent on the home theater system = 25 u - 10 u - 2 u = 13 u
13 u = 390
1 u = 390 ÷ 13 = 30
Her salary
= 25 u
= 25 x 30
= $750
Answer(s): $750
