Answer: You should pay $13.00
Step-by-step explanation:
1. Calculate the total cost of the chocolate milkshakes for your friends: 5.00 x 3 = 15.00
2. Subtract the total cost of the chocolate milkshakes from the total bill: 65.00 - 15.00 = $50.00
3. Add the cost of your soda to the remaining bill:$50.00 + 2.00 = 52.00
4. Split the remaining bill evenly among the four of you: 52.00 / 4 = 13.00
