Four friends decided to split a check at a restaurant. However, one forgot his wallet, so the others offered to cover his portion. If each one was supposed to contribute $24 to the check, how much more, in dollars, will each person have to pay to cover their share plus the third friend's?

The correct answer is 8.
Explanation: Since each of the three remaining friends will be covering the $24 not covered by the absentminded friend, each will be responsible for 1/3 of what the wallet-less friend will owe. Thus, each will owe an additional $8, as 1/3 of $24 is $8.
