18 =
78 78 of the remaining salary =
25 of the total salary
7x28x2 of the remaining salary =
2x75x7 of the total salary
1416 of the remaining salary =
1435 of the total salary
Total salary = 35 u
Amount left = 14 u
Amount spent on the muffin maker = 16 u - 14 u = 2 u
Amount spent on the washing machine = 35 u - 14 u - 2 u = 19 u
19 u = 380
1 u = 380 ÷ 19 = 20
Her salary
= 35 u
= 35 x 20
= $700
Answer(s): $700
