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
