After 2 |

6 u |
+ 207 |
35 x 460= 276
460 - 276 = 184
25% x 8 u
=
25100 x 8 u
= 2 u
25% x 276
=
25100 x 276
= 69
276 - 69 = 207
184 + 69 = 253
If Julie received another $176 in the end, Julie and Mary would have the same amount of money.
6 u + 207 = 4 u + 253 + 176
6 u - 4 u = 253 + 176 - 207
2 u = 222
1 u = 222 ÷ 2 = 111
Amount that Julie had at first
= 5 u + 460
= 5 x 111 + 460
= 555 + 460
= $1015
Answer(s): $1015
