A bakery works out a demand function for its chocolate chip cookies and finds it to be q=D(x)=906-13x, where q is the quantity of cookies sold when the price per cookie, in cents, is x. Use this information to answer parts a) through f). a) Find the elasticity. E(x)= b) At what price is the elasticity of demand equal to 1? (Round to the nearest cent as needed.) c) At what prices is the elasticity of demand elastic? OA. Greater than 35¢ OB. Prices cannot be elastic in this case OC. Less than 35¢ OD. Prices are elastic at all values. d) At what prices is the elasticity of demand inelastic? OA. Greater than 35 OB. Less than 35g OC. Prices cannot be inelastic in this case OD. Prices are inelastic at all values e) At what price is the revenue a maximum? x=¢ (Round to the nearest cent as needed. Use a comma to separate answers as needed.) f) At a price of 17€ per cookie, will a small increase in price cause the total revenue to increase or decrease? O Decrease O Increase

8. The interaction of individual choices Because eels are highly endangered as a species, many governments enact laws prohibiting fishing along their migration route. Initially, eel fishers complain about this restriction on the locations they can fish, but after a while they notice that the number eels swimming outside regulated areas is much higher than it was before. With the laws in place, eel fishers end up catching a greater quantity of eels than they did prior to the enactment of the laws. Which of the following principles of economic interaction best describes this scenario? O Markets allocate goods effectively. O When markets do not achieve efficiency, government intervention can improve overall welfare. O There is a tradeoff between equality and efficiency. O Markets usually lead to efficiency.

2. Determining opportunity cost Juanita is deciding whether to buy a skirt that she wants, as well as where to buy it. Three stores carry the same skirt, but it is more convenient for Juanita to get to some stores than others. For example, she can go to her local store, Discounted price located 15 minutes away from where she works, and pay a Marked-up price marked-up price of $122 for the skirt: Juanita's office Original price Travel Time Each Way Price of a Skirt Store (Minutes) (Dollars per skirt) Local Department Store 15 122 Across Town 30 90 Neighboring City 60 78 Juanita makes $60 an hour at work. She has to take time off work to purchase her skirt, so each hour away from work costs her $60 in lost income. Assume that returning to work takes Juanita the same amount of time as getting to a store and that it takes her 30 minutes to shop. As you answer the following questions, ignore the cost of gasoline and depreciation of her car when traveling. Complete the following table by…

8. Suppose that you have a big test on Monday and you plan to spend the weekend studying. On Saturday, your friend invites you to spend the day at a water park. It's the last weekend that the park will be open for the year. You'd really like to go to the park, but you're worried that you won't have enough time to study on Sunday. What are the possible tradeoffs of each choice-going to the water park or staying home to study?

6. For your birthday, you receive a hamper from your friend, which contains food and drink. They have chosen to buy you 8 packs of hot chocolate and 10 packs of luxury biscuits. Unfortunately, the hot chocolate is not milk chocolate and the biscuits are chocolate chip and not your favourite ginger biscuits! They haven't provided the receipt, but you return to the shop where the hamper was bought and ask to exchange the items. Each pack of hot chocolate was priced at £5 and each pack of biscuits was priced at £6. You face a utility function of U (Hċ, B) = H²B. When you return to the shop, you see that all of the biscuits are now half price, but all of the types of hot chocolate haven't changed in price. You are able to exchange your biscuits and hot chocolate, but can only receive a refund based on the current marked price of the products in the shop. Given this information and assuming hot chocolate is on the horizontal axis and your aim to maximise utility, what should you do? (a) You…
