Hi GMAT_mission,

We're told that 15 people contributed a total of $20.00 toward a gift and each person contributed at least $1.00. We're asked for the maximum possible amount that any one person could have contributed. This is essentially a 'limit' question and comes down to a bit Arithmetic and a bit of logic.

To maximize the amount that one person could give, we have to minimize the amounts that everyone else gives. We know the minimum amount is $1.00, and if 14 of the 15 people gave just $1, then that would total (14)($1) = $14. This leaves $6 for the last person to give.

Final Answer: D

If 14 people contributed 1 dollar, then the remaining person would have had to contribute 6 dollars.
