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 Fiona received another $298 in the end, Fiona and Lynn would have the same amount of money.
6 u + 216 = 4 u + 264 + 298
6 u - 4 u = 264 + 298 - 216
2 u = 346
1 u = 346 ÷ 2 = 173
Amount that Fiona had at first
= 5 u + 480
= 5 x 173 + 480
= 865 + 480
= $1345
Answer(s): $1345
