Question

A college student realized 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 4 others months he spent $65,$85,50, and $40 round your answer to the nearest two decimal places it necessary

Answer 1

To calculate how much the college student can spend in December while maintaining a mean of $50 per month for the remaining 5 months of the year, we need to consider the total amount spent in the previous four months and the desired mean.

Let's denote the amount the student can spend in December as "x." The total amount spent in the previous four months is $65 + $85 + $50 + $40 = $240.

To maintain a mean of $50 per month for the remaining 5 months, the sum of the amounts spent in those months should be (5 * $50) - $240.

(5 * $50) - $240 = $250 - $240 = $10

Therefore, the student can spend $10 in December to maintain a mean of $50 per month for the remaining 5 months of the year.
