After 2 |

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 Gem received another $256 in the end, Gem and Kimberly would have the same amount of money.
6 u + 216 = 4 u + 264 + 256
6 u - 4 u = 264 + 256 - 216
2 u = 304
1 u = 304 ÷ 2 = 152
Amount that Kimberly had at first
= 5 u
= 5 x 152
= $760
Answer(s): $760
