Cost of Date: $50
Cost of Hanging Out with Friends: $30
Date     Total Utility                 Hanging Out with Friends   Total Utility
0    0                     0                     0
1    110                  1                     110
2    265                 2                     203
3    394                 3                     288
4    421                  4                     352
5    440                 5                     400
