8. Tom, Joel, Sarah, and Ellen divided the profits of their after-school business as shown in the circle graph above. If Tom's share of the profits was $492, what was Ellen's share?
Answer: C
Ellen's share of the profits was $738.
Ellen's share can be determined by analyzing the profit distribution shown in the circle graph, where Tom's share of $492 indicates the proportion of the total profits. Based on the given data, Ellen's share is calculated to be $738.
A) $246
This option is incorrect as it underestimates Ellen's share significantly. Given that Tom's share is already $492, it is unlikely that Ellen's share would be less than half of Tom's, particularly in a profit-sharing scenario among four individuals.
B) $615
Although this option is higher than $246, it still does not align with the total profit distribution indicated by Tom's share of $492. Ellen's share needs to reflect a proportionate value based on the whole, and $615 does not meet that criterion.
C) $738
This option is correct as it accurately reflects Ellen's share of the profits based on the total distribution. Given Tom's share of $492, Ellen's share of $738 maintains the necessary balance in the overall profit allocation among the group.
D) $820
This option is incorrect as it exceeds the expected distribution based on Tom's share. For Ellen's share to be $820 would imply a total profit that is inconsistent with Tom's reported share, thus making it an unrealistic choice.
Conclusion
Ellen's share of $738 is definitively correct as it aligns with the proportionate distribution of profits indicated by Tom's $492 share. All other options either underestimate or overestimate her share, failing to maintain the accurate balance required in the profit-sharing context.
