Q: The dinner bill for 6 friends came to $150. Silas said he would pay for half of the bill and the remaining friends could split the rest of the bill and leave a 10% tip for the whole meal. How many dollars will one of the friends pay?
A: 18
Explain how we arrive at this answer:
Explanation: Silas paid half = 150 / 2 = 75. Remaining bill paid by 5 friends = 75 + 10% of 150 = 75 + 15 = 90. Each person will pay 1 / 5 which is 90 / 5 = 18. Each friend will pay $18.
