# Question: The Walk for Kids is an annual fund raising event

The Walk for Kids is an annual fund- raising event that raises money for research on children’s blood disorders. The Walk costs \$ 120,000 to stage even if nobody shows up. To encourage people to participate, each walker is given a T-shirt that costs the Walk \$ 8.00 and refreshments that cost an average of \$ 10 per person. This year, the organizers of the Walk got a \$ 20,000 grant from the City Foundation to offset part of the costs associated with staging the Walk. The Walk raises money by asking each walker to pay \$ 10 to register and requires each walker to solicit sponsors who agree to pay \$.75 (seventy-five cents) per mile for each of the 10 miles that the walker completes. In the past, all of the walkers have completed the ten- mile course and have had an average of 20 sponsors.
