Can you break down the solution for me for this math problem: For 6 weeks in the summer, Erica treats herself to 1 ice cream cone from the ice cream truck.  Monday, Wednesday and Friday she gets a $2.00 orange creamsicle.  Tuesday and Thursday she gets a $1.50 ice cream sandwich.  Saturday and Sunday she gets a $3.00 Nutty-Buddy.  How much money does she spend on ice cream in 6 weeks?
