35 x 300= 180
300 - 180 = 120
25% x 8 u
=
25100 x 8 u
= 2 u
25% x 180
=
25100 x 180
= 45
180 - 45 = 135
120 + 45 = 165
If Vanessa received another $114 in the end, Vanessa and Emily would have the same amount of money.
6 u + 135 = 4 u + 165 + 114
6 u - 4 u = 165 + 114 - 135
2 u = 144
1 u = 144 ÷ 2 = 72
Amount that Emily had at first
= 5 u
= 5 x 72
= $360
Answer(s): $360
