37 =
47 47 of the remaining salary =
29 of the total salary
4x17x1 of the remaining salary =
2x29x2 of the total salary
47 of the remaining salary =
418 of the total salary
Total salary = 18 u
Amount left = 4 u
Amount spent on the stand mixer = 7 u - 4 u = 3 u
Amount spent on the television = 18 u - 4 u - 3 u = 11 u
11 u = 440
1 u = 440 ÷ 11 = 40
Her salary
= 18 u
= 18 x 40
= $720
Answer(s): $720
