Ten friends went to an ice cream parlour, and everyone decided to contribute equally to the total bill of $50. If one of the friends had a coupon for 10% off the total bill, and if each friend still contributed equally after the coupon was applied to the bill, how much did each friend pay?	Choices
A) 4.2  B) 4.5  C) 4  D) 4.8  E) 4.6
At the non-discounted price, each friend would pay $5, as $50 divided by 10 friends is $5 per friend. But if the bill is 10% off, then each friend would pay 10% less. 10% of $5 is $0.5, so each friend saves $0.5 and pays the remaining $4.5   CORRECT OPTION:OPTION 4.5
