7. There is a road named High Street with 800m long. There are two grocery shops: Woolworths located at the left end and Coles located at the right end. 4800 customers are uniformly distributed along High Street. To make our life easier, assume both grocery stores sell the same product, and consumers demand just one unit of the product. Traveling to a grocery shop is costly, and the cost of traveling is 4 cents per meter. Suppose the price of the product is $10 at Woolworths, and $12 at Coles. Then customers will purchase the product from Woolworths.

Sean's Fire Engines is the sole seller of fire engines in the fictional country of Pyrotania. Initially, Sean produced five fire engines, but he has decided to increase production to six fire engines. The following graph shows the demand curve Sean faces. As you can see, to sell the additional engine, Sean must lower his price from $160,000 to $120,000 per fire engine. Note that while Sean gains revenue from the additional engine he sells, he also loses revenue from the initial five engines because he sells them all at the lower price. Use the purple rectangle (diamond symbols) to shade the area representing the revenue lost from the initial five engines by selling at $120,000 rather than $160,000. Then use the green rectangle (triangle symbols) to shade the area representing the revenue gained from selling an additional engine at $120,000.

Say in a market we haveDemand is P = 5 – 0.005QSupply is P = 0.00125Qa-you will have a graph with price on the vertical axis and quantity on the horizontal axis formost parts of this problem. You will want to show intercept values and equilibrium values withthe specific values from the problem (when you graph the supply show it go out at least to thesame level of Q as the Q intercept for the demand curve).b-what are the equilibrium price and quantity traded in the market?c-say the government levies an excise tax in the market of 50 cents that renders the supply tonow be P = .00125Q + 0.5 (essentially the supply curve shifts up by 50 cents at each quantity).What are the new equilibrium price and quantity traded in the market with this excise tax?d-did the market price increase by as much as the 50 cent tax?

5. Darnell owns a water pump. Because pumping large amounts of water is harder than pumping small amounts, the cost of producing a bottle of water rises as he pumps more, Here is the cost he incurs to produce each bottle of water: Cost of first bottle: $1 Cost of second bottle: $4 Cost of third bottle: $7 Cost of fourth bottle: $9 From this information, complete the following table by denving Darne/'s supply schedule.
