Fraction of the remaining salary left
= 1 -
25 =
35 35 of the remaining salary =
18 of the total salary
3x15x1 of the remaining salary =
1x38x3 of the total salary
35 of the remaining salary =
324 of the total salary
Total salary = 24 u
Amount left = 3 u
Amount spent on the muffin maker = 5 u - 3 u = 2 u
Amount spent on the notebook = 24 u - 3 u - 2 u = 19 u
19 u = 380
1 u = 380 ÷ 19 = 20
Her salary
= 24 u
= 24 x 20
= $480
Answer(s): $480
