Final answer:
Each person, Mike, Johnny, and Sam, would spend 12.96 when the total bill of 32.40 with an additional 20% tip is split equally among them.
Step-by-step explanation:
To calculate how much each person spent when Mike, Johnny, and Sam ate out and split the total bill equally after leaving a 20% tip, we first need to find the total amount spent by all three before the tip, and then calculate the tip amount and the final individual contributions.
Step-by-step Calculation:
- First, add the individual totals to get the collective total before the tip: 8.95 (Mike) + 12.50 (Johnny) + 10.95 (Sam) = 32.40.
- Next, figure out the total tip amount by calculating 20% of the collective total: 0.20 x 32.40 = 6.48.
- Add the tip to the collective total to find the final amount due: 32.40 + 6.48 = 38.88.
- Divide the final amount by the number of people to find out how much each person should pay: 38.88 / 3 = 12.96.
Thus, each person would spend 12.96 when the bill is split equally after including the 20% tip.
