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.

2. Individual demand and consumer surplus Consider the market for electric vehicles. The market price of each electric vehicle is $135,000, and each consumer demands no more than one electric vehicle. Suppose that Tim is the only consumer in the electric vehicle market. Their willingness to pay for an electric vehicle is $270,000. Based on Tim's willingness to pay, the following graph shows his demand curve for electric vehicles. Shade the area representing Tim's consumer surplus using the green rectangle (triangle symbols).
