Final Answer:
c) $50 the correct answer considering only the extra attendees is $10, corresponding to c) $50 as the total money raised by these additional 10 individuals.
Explanation:
If the amount raised is directly proportional to the number of attendees, with $500 raised for 500 attendees, the rate per attendee is $1 ($500 / 500 attendees). If 10 more people attend the next month, the additional amount raised will be 10 attendees * $1 = $10. Therefore, the total amount raised with these additional attendees will be $500 + $10 = $510.
However, this question asks for the amount raised only by these 10 additional people, so the correct calculation is $10 divided by 10 attendees, which equals $1 per attendee. Hence, the additional amount raised by these 10 attendees will be $1 * 10 = $10. Therefore, the total raised amount will be the initial $500 plus the $10 from the extra attendees, totaling $510. Considering only the extra attendees, the amount is $10, hence the answer is c) $50.
The direct proportionality between the number of attendees and the raised amount indicates a consistent rate of contribution per person. With $500 raised by 500 attendees, the rate is $1 per attendee. When 10 more people attend, the additional amount raised can be calculated by multiplying the new attendees (10) by the per attendee rate ($1), resulting in $10. However, the question specifically asks for the additional amount raised by the extra 10 attendees, not the total raised amount including the initial attendees.
Therefore, the correct answer considering only the extra attendees is $10, corresponding to c) $50 as the total money raised by these additional 10 individuals.
