Practice Question
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 Choices
- A: $2,460
- B: $615
- C: $738
- D: $820
Correct Answer: A
Rationale: Identify Tom’s percentage from the chart
The circle graph shows:
Tom = 10%
Ellen = 50%
Sarah = 25%
Joel = 15%
Relate Tom’s percentage to his profit
Tom’s 10% share is worth $492.
Find the total profit
Since 10% corresponds to $492:
Total Profit
=
Tom’s Share
Tom’s Percentage
=
492
0.10
=
4920
Total Profit=
Tom’s Percentage
Tom’s Share
=
0.10
492
=4920
Find Ellen’s share
Ellen has 50% of the total profit:
Ellen’s Share
=
0.50
×
4920
=
2460
Ellen’s Share=0.50×4920=2460
