1. Maria can read 20 pages of economics in an hour. She can also read 50 pages of

2. Pat and Kris are roommates. They spend most of their time studying (of course), but they
leave some time for their favorite activities: making pizza and filtering water. Pat takes
4 hours to filter a bottle of water and 2 hours to make a pizza. Kris takes 6 hours to filter

off? What is the lowest price? Explain.
3. Suppose a gardener produces both green beans and corn in her garden. If she must give
up 14 bushels of corn to get 5 bushels of green beans, then calculate her opportunity cost
of 1 bushel of green beans.
4. Mike and Sandy are two woodworkers who both make tables and chairs. In one month,
Mike can make 4 tables or 20 chairs, where Sandy can make 6 tables or 18 chairs. Given
this, calculate the opportunity cost of 1 table for both Mike and Sandy.
