Question

A college student realized that he was spending too much money on music. For the remaining 5 months of the year his goal is to spend a mean of $50 a month towards music. How much can he spend in December, taking into consideration that in the other 4 months he spent $95, $60, $40, and $40, respectively? Round your answer to two decimal places, if necessary.

Answer 1

$15 because a mean would allow him to spend $250 over the five months BUT he has already spent $235.

$250 - $235 = $15
