Three people go to a restaurant. Their bill comes to $78.00. They decide to split the cost. One person pays $4.50; the next person pays 3 times that amount. How much will the third person have to pay?

Detailed Explanation

First, figure out how much the second person paid: 4.50 × 3 = 13.5

Then, calculate the total amount contributed by the first two people:

4.50 + 13.50 = 18.00

Finally, calculate how much the third person will have to contribute by subtracting the amount paid (18.00) from the original amount owed (78.00):

78.00 - 18.00 = 60.00

Then, calculate the total amount contributed by the first two people:

4.50 + 13.50 = 18.00

Finally, calculate how much the third person will have to contribute by subtracting the amount paid (18.00) from the original amount owed (78.00):

78.00 - 18.00 = 60.00
