Tarzan and jane adopted a new born monkey and called him bongo. unlike other monkeys, bongo likes dried strawberries and consumes 20 strawberries per week. the nearest strawberry producer to tarzan and jane’s house (tree in fact) is far away. tarzan and jane estimate that they’ll have to use a day of their neighbor’s elephant every time they shop from that farmer. the neighbor charges them $40 for each trip. one strawberry costs $4. jane also calculates the holding cost of 1 strawberry as $1 per week, because strawberries occupy a lot of place in their tree. assume that tarzan and jane will never let bongo be hungry (i. e., no backorders). p. s. in tarzan’s forest, each week has 5 days. when should tarzan and jane place an order (i. e., calculate the rop)?

"in the electricity industry, low average total costs are obtained only through large-scale production. in other words, the initial cost of setting up all the necessary wiring makes it risky and, most likely, unprofitable for competitors to enter the market. throughout much of the 20th century, many people viewed south africa’s de beers group as a monopoly because it controlled a large percentage of diamond production and sales. patents are granted to inventors of a product or process for a certain number of years. the reason for this is to encourage innovation in the economy. without the existence of patents, it is argued, research and development for improved electronics is unlikely to take place, since there’s nothing preventing another firm from stealing the idea, copying the product, and producing it without incurring the devel opment costs."which of the following best explains the barriers to entry that exist in this scenario? increasing returns to scale legal barriers exclusive ownership of a necessary resource
