Question

Four members of the Kaplan family will take a river trip down the Colorado River in Colorado State Park. The rafting company charges $10 per person for a half-day river trip, or $100 flat rate for a half-day river trip. The raft can hold up to 10 people. How much will the trip cost the Kaplan family at the per person rate? How many people must be on the river trip to make the flat rate less expensive than the per person rate?

Answer 1

4*10 = 40

10 * 10 = 100
so eleven, but the raft only holds ten :)
