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 Emily received another $252 in the end, Emily and Vanessa would have the same amount of money.
6 u + 225 = 4 u + 275 + 252
6 u - 4 u = 275 + 252 - 225
2 u = 302
1 u = 302 ÷ 2 = 151
Amount that Emily had at first
= 5 u + 500
= 5 x 151 + 500
= 755 + 500
= $1255
Answer(s): $1255
