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

Answer 2

He can spend $15 in December.

What is mean?

• "It is the average of the numbers."
• "To calculate: add up all the numbers, then divide by how many numbers there are."

For given question,

For the remaining 5 months of the year his goal is to spend a mean of $50 a month towards music.

Out of 5 months, in the other 4 months he spent $95, $60, $40, and $40, respectively.

Let he spends 'x' dollars in December.

Using the formula of mean,

$\Rightarrow \frac{95+60+40+40+x}{5} =50\\\\\Rightarrow 235+x=250\\\\\Rightarrow x=250-235\\\\\Rightarrow x=15$

Therefore, he can spend $15 in December.
