Surprise

I have spent a total of $5.20 for the past 3 days. Now I am able to spend $20 per day for the remaining 2 days of the month and still stay on my target of $10/day.

To add on to my happiness, I received a gift of $100 cash today. To pamper my girlfriend(which I have not done for a long time), I will spend this $100 purely on dates and not save a single cent of it. However, this $100 would be spent carefully in order to achieve maximum utility. This is how I am going to spend it:

2 sessions of weekend movies : $40
Chips or candies for movie : $9
One for one pasta : $25
Girlfriend's favourite dessert at ion : $10
A pair of Universal studio after hours tickets : $16

Total: $100 (to be spent over 2 weekends)
