Final answer:
The college student can spend $65 in December to meet his goal of spending a mean of $60 a month on video games for the remaining 5 months.
Step-by-step explanation:
To find out how much the college student can spend in December in order to meet his goal of spending a mean of $60 a month on video games for the remaining 5 months of the year, we need to calculate the total amount he can spend for the 5 months so far.
Given that the student has already spent $65, $95, $20, and $55 in the first 4 months respectively, we can calculate the total amount spent by adding these amounts together: $65 + $95 + $20 + $55 = $235.
To find out the remaining amount that the student can spend for the remaining 5 months, we subtract the total amount spent so far from the goal for the 5 months: $60 * 5 - $235 = $65.
Therefore, the college student can spend $65 in December to meet his goal of spending a mean of $60 a month on video games for the remaining 5 months of the year.
