15 =
45 45 of the remaining salary =
29 of the total salary
4x15x1 of the remaining salary =
2x29x2 of the total salary
45 of the remaining salary =
418 of the total salary
Total salary = 18 u
Amount left = 4 u
Amount spent on the food processor = 5 u - 4 u = 1 u
Amount spent on the notebook = 18 u - 4 u - 1 u = 13 u
13 u = 650
1 u = 650 ÷ 13 = 50
Her salary
= 18 u
= 18 x 50
= $900
Answer(s): $900
