Fraction of the remaining salary left
= 1 -
14 =
34 34 of the remaining salary =
27 of the total salary
3x24x2 of the remaining salary =
2x37x3 of the total salary
68 of the remaining salary =
621 of the total salary
Total salary = 21 u
Amount left = 6 u
Amount spent on the muffin maker = 8 u - 6 u = 2 u
Amount spent on the dishwasher = 21 u - 6 u - 2 u = 13 u
13 u = 390
1 u = 390 ÷ 13 = 30
Her salary
= 21 u
= 21 x 30
= $630
Answer(s): $630
