Fraction of the remaining salary left
= 1 -
18 =
78 78 of the remaining salary =
27 of the total salary
7x28x2 of the remaining salary =
2x77x7 of the total salary
1416 of the remaining salary =
1449 of the total salary
Total salary = 49 u
Amount left = 14 u
Amount spent on the water heater = 16 u - 14 u = 2 u
Amount spent on the washing machine = 49 u - 14 u - 2 u = 33 u
33 u = 1650
1 u = 1650 ÷ 33 = 50
Her salary
= 49 u
= 49 x 50
= $2450
Answer(s): $2450
