17 =
67 67 of the remaining salary =
29 of the total salary
6x17x1 of the remaining salary =
2x39x3 of the total salary
67 of the remaining salary =
627 of the total salary
Total salary = 27 u
Amount left = 6 u
Amount spent on the water heater = 7 u - 6 u = 1 u
Amount spent on the dishwasher = 27 u - 6 u - 1 u = 20 u
20 u = 300
1 u = 300 ÷ 20 = 15
Her salary
= 27 u
= 27 x 15
= $405
Answer(s): $405
