35 x 440= 264
440 - 264 = 176
25% x 8 u
=
25100 x 8 u
= 2 u
25% x 264
=
25100 x 264
= 66
264 - 66 = 198
176 + 66 = 242
If Abi received another $212 in the end, Abi and Gillian would have the same amount of money.
6 u + 198 = 4 u + 242 + 212
6 u - 4 u = 242 + 212 - 198
2 u = 256
1 u = 256 ÷ 2 = 128
Amount that Abi had at first
= 5 u + 440
= 5 x 128 + 440
= 640 + 440
= $1080
Answer(s): $1080
