Refer the above demand curve, the demand function is: a. Q = 40 ? 2P b. Q = 80 ? 0.5P c. Q = 40 ? 0.5P d. Q = 80 ? 2P Assume peanut butter and jelly are complements. Ceteris paribus, an increase in the price of peanut butter will cause a (an): a. leftward shift in the demand curve for jelly. b. rightward shift in the demand curve for jelly. c. upward movement along the demand curve for jelly. d. downward movement along the demand curve for jelly.

Step 1
If peanut butter and jelly are complements, it means that they are typically consumed together. So, an increase in the price of peanut butter would make it more expensive for consumers to buy peanut butter and jelly together. Show more…

The price of peanuts increases. At the same time, we see the price of Jelly rise. How does this affect the market for peanut butter? A. the demand curve will shift to the left; the supply curve will shift to the left. B. the demand curve will shift to the left; the supply curve will shift to the right. C. the demand curve will shift to the right; the supply curve will shift to the left. D. the demand curve will shift to the right; the supply curve will shift to the right.

The demand curve for a product is given by $q=$ $120,000-500 p$ and the supply curve is given by $q=$ $1000 p$ for $0 \leq q \leq 120,000,$ where price is in dollars. (a) At a price of $\$ 100,$ what quantity are consumers willing to buy and what quantity are producers willing to supply? Will the market push prices up or down? (b) Find the equilibrium price and quantity. Does your answer to part (a) support the observation that market forces tend to push prices closer to the equilibrium price?
