Raphael is a skilled toy maker who is able to produce both trucks and kites. He has 8 hours a day to produce toys. The following table shows the daily output resulting from various possible combinations of his time. Choice Hours Producing Produced (Trucks) (Kites) (Trucks) (Kites) A 8 0 4 0 B 6 2 3 10 C 4 4 2 16 D 2 6 1 19 E 0 8 0 20   On the following graph, use the blue points (circle symbol) to plot Raphael's initial production possibilities frontier (PPF). ( attached image)       Suppose Raphael is currently using combination D, producing one truck per day. His opportunity cost of producing a second truck per day is( 1, 3, 16, 19 kites) per day.   Now, suppose Raphael is currently using combination C, producing two trucks per day. His opportunity cost of producing a third truck per day is ( 1,6,10, or 16 kites)   per day.   From the previous analysis, you can determine that as Raphael increases his production of trucks, his opportunity cost of producing one more truck ( increase, decreases, or remain constant)    .

I am struggling with the graphs

2. Determining opportunity cost Suppose that Ciana is deciding whether or not to buy a pair of sneakers that she has been researching online, and also the best place to make her purchase. Three different stores in the area sell the sneakers she likes, but some stores are more convenient for Ciana to reach than others. One option is her local shoe store located only 15 minutes away from where she works, where they charge a marked-up price of $112 for the sneakers:   Ciana earns an hourly wage of $42 at her job. In order to purchase her sneakers she will have to take time off work, so each hour away from her job costs her $42 in lost income. Assume that Ciana’s travel time is the same each way (to and from the store) and that it will take her 30 minutes once she reaches a store to complete her shopping. Assume throughout the question that Ciana incurs no additional costs other than the sneakers, such as gas. Complete the following table by computing the opportunity cost of…
