35 x 180= 108
180 - 108 = 72
25% x 8 u
=
25100 x 8 u
= 2 u
25% x 108
=
25100 x 108
= 27
108 - 27 = 81
72 + 27 = 99
If Wendy received another $206 in the end, Wendy and Nicole would have the same amount of money.
6 u + 81 = 4 u + 99 + 206
6 u - 4 u = 99 + 206 - 81
2 u = 224
1 u = 224 ÷ 2 = 112
Amount that Wendy had at first
= 5 u + 180
= 5 x 112 + 180
= 560 + 180
= $740
Answer(s): $740
