37 =
47 47 of the remaining salary =
15 of the total salary
4x17x1 of the remaining salary =
1x45x4 of the total salary
47 of the remaining salary =
420 of the total salary
Total salary = 20 u
Amount left = 4 u
Amount spent on the kettle = 7 u - 4 u = 3 u
Amount spent on the refrigerator = 20 u - 4 u - 3 u = 13 u
13 u = 325
1 u = 325 ÷ 13 = 25
Her salary
= 20 u
= 20 x 25
= $500
Answer(s): $500
