35 x 420= 252
420 - 252 = 168
25% x 8 u
=
25100 x 8 u
= 2 u
25% x 252
=
25100 x 252
= 63
252 - 63 = 189
168 + 63 = 231
If Winnie received another $254 in the end, Winnie and Fanny would have the same amount of money.
6 u + 189 = 4 u + 231 + 254
6 u - 4 u = 231 + 254 - 189
2 u = 296
1 u = 296 ÷ 2 = 148
Amount that Winnie had at first
= 5 u + 420
= 5 x 148 + 420
= 740 + 420
= $1160
Answer(s): $1160
