35 x 480= 288
480 - 288 = 192
25% x 8 u
=
25100 x 8 u
= 2 u
25% x 288
=
25100 x 288
= 72
288 - 72 = 216
192 + 72 = 264
If Wendy received another $194 in the end, Wendy and Julie would have the same amount of money.
6 u + 216 = 4 u + 264 + 194
6 u - 4 u = 264 + 194 - 216
2 u = 242
1 u = 242 ÷ 2 = 121
Amount that Julie had at first
= 5 u
= 5 x 121
= $605
Answer(s): $605
