35 x 500= 300
500 - 300 = 200
25% x 8 u
=
25100 x 8 u
= 2 u
25% x 300
=
25100 x 300
= 75
300 - 75 = 225
200 + 75 = 275
If Vanessa received another $184 in the end, Vanessa and Winnie would have the same amount of money.
6 u + 225 = 4 u + 275 + 184
6 u - 4 u = 275 + 184 - 225
2 u = 234
1 u = 234 ÷ 2 = 117
Amount that Vanessa had at first
= 5 u + 500
= 5 x 117 + 500
= 585 + 500
= $1085
Answer(s): $1085
