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? Give me reasons, before answering the question

Mon, Wed, Fri she gets a $2.00 orange creamsicle so that's 3 days * $2 / day = $6.00. Tue and Thur she gets a $1.50 ice cream sandwich so that's 2 days * $1.50 / day = $3.00. Sat and Sun she gets a $3.00 nutty - buddy so that's 2 days * $3 / day = $6.00. In one week she spends $6 + $3 + $6 = $15.00. Over 6 weeks she spends 6 weeks * $15 / week = $90.00. So the final answer is 90.
