23 x 285= 190
285 - 190 = 95
20% x 5 u
=
20100 x 5 u
= 1 u
20% x 190
=
20100 x 190
= 38
190 - 38 = 152
95 + 38 = 133
If Julie received another $297 in the end, Julie and Elyse would have the same amount of money.
4 u + 152 = 2 u + 133 + 297
4 u - 2 u = 133 + 297 - 152
2 u = 278
1 u = 278 ÷ 2 = 139
Amount that Elyse had at first
= 3 u
= 3 x 139
= $417
Answer(s): $417
