A corn farmer is experiencing lower and lower yields of their corn crop every year. They hypothesize that their farmland has become depleted of nitrogen, which is a nutrient required for plants to grow. The farmer recently learned about plants that can capture unusable nitrogen from the air and convert it into usable nitrogen in the soil. (Fun fact: this is accomplished through a symbiosis with bacteria.) The farmer decides to plant these “nitrogen-fixing” plants in some of their fields. What experimental results would support the null hypothesis?

You have an income of $120 per week and own a car that costs $2 per mile to drive. You choose to drive 50 miles per week. a) Draw your budget constraint between "miles driven" and "all other goods," with "all other goods" measured in dollars. Show your optimum point. b) Suppose you are offered the opportunity to purchase for $60 a car that costs 50 cents a mile to drive. If you do this, you'll throw your old car away. Draw the budget constraint that results if you buy the new car. Note that the two budget constraints cross at (40, 40). c) Would you buy the new car? Defend your answer using indifference curves.
