Math Help

KVMS has 580 students, all but 47 participate in the Kougar Prowl. A grand total of 6929.00$ is raised in this year.

A, How much money is raised, by the students that walked, per capita?

B. What would the total have been if the other 47 students had matched the per capita amounts?

C. In 2006 a total of 13,533.13$ was raised for Kougar Prowl. How much would it be per capita, with all the students participating? (round to the nearest dollar.)

Thanks bunches! Oh, and I need the answers to all of them. Also, it’s not for a grade, I get a free hacky sack.
