Final answer:
To determine how much each person owes, calculate the total tip amount by multiplying the total check by 15%, add it to the total check, divide by the number of people, and round to the nearest cent resulting in $38.67 per person.
Step-by-step explanation:
To calculate how much each person should pay, including tip, for the dinner when the total check is $134.50 and the group decides to tip the waiter 15%, follow these steps:
Calculate the total amount of tip by converting the percentage to a decimal and then multiplying by the total check amount. Tip = 0.15 × $134.50 = $20.175.
Add the tip to the total check to find the grand total. Grand Total = $134.50 + $20.175 = $154.675.
Divide the grand total by the number of people to find out how much each person should pay. Each Person Pays = $154.675 ÷ 4 = $38.66875.
Round the amount to the nearest cent. Each Person Pays: $38.67.
Therefore, you and each of your friends should pay $38.67 to cover the bill including the tip.
