After 2 |

6 u |
+ 135 |
35 x 300= 180
300 - 180 = 120
25% x 8 u
=
25100 x 8 u
= 2 u
25% x 180
=
25100 x 180
= 45
180 - 45 = 135
120 + 45 = 165
If Gabby received another $266 in the end, Gabby and Nicole would have the same amount of money.
6 u + 135 = 4 u + 165 + 266
6 u - 4 u = 165 + 266 - 135
2 u = 296
1 u = 296 ÷ 2 = 148
Amount that Gabby had at first
= 5 u + 300
= 5 x 148 + 300
= 740 + 300
= $1040
Answer(s): $1040
