DAY 415

Doofus and Goofus were playing a game in which the winner won $1.00 for each victory.  In the end, Doofus won $7 and Goofus won 7 games. How many games were played?

Answer:

21 ........... If Doofus won $7, he must have won 7 more games than Goofus. If Goofus won seven games, Doofus must have won 14 games.  14 + 7 = 21.
