6 u |
+ 162 |
35 x 360= 216
360 - 216 = 144
25% x 8 u
=
25100 x 8 u
= 2 u
25% x 216
=
25100 x 216
= 54
216 - 54 = 162
144 + 54 = 198
If Xylia received another $214 in the end, Xylia and Cathy would have the same amount of money.
6 u + 162 = 4 u + 198 + 214
6 u - 4 u = 198 + 214 - 162
2 u = 250
1 u = 250 ÷ 2 = 125
Amount that Cathy had at first
= 5 u
= 5 x 125
= $625
Answer(s): $625
