It is a circle graph question.

The city book club raised $560 to buy books for the school library. The greatest amount of money come from a walk-a-thon.
A crafts fair and a bake sale raised equal amount of money.

The amount received from club dues was twice as much as the amount raised from bake sale
what fraction of money was raised by a walk-a-thon?
What fraction of money came from club dues?
How much more money would the club have had to receive from the bake sale to match walk-a-thon?
A company promised to match the total amount that the book club received from both the crafts fair and bake sale. How much the company give?

I don't see enough information to solve it above. There is no realationship between walkathon recepits except they were the greatest.
