## Good GuessMath brain teasers require computations to solve.
In order to win a free laptop computer, students had to guess the exact numbers of gumballs in a jar. The students guessed 45, 41, 55, 50, and 43, but nobody won. The guesses were off by 3, 7, 5, 7, and 2 (given in no particular order). From this information, can you determine the number of gumballs in the jar?
