Jonathan is considering opening a shop for online baseball memorabilia. He has two options. He can build the web site himself and only pay for hosting. This would cost him $2,000/y ear. The average item for sale is $4.01. Average costs associated with each sale are $2.99. His second option is to use an existing e-commerce service. This incurs an additional monthly cost of $15/month. The site takes a cut of his sales of $0.22/ item, so he is planning on also increasing his prices by $0.46/ item. The remaining costs stay the same. How many items does he need to sell using his own site in order to break even? a. 1960.78 b. 2137.25 c. -1960.78 d. 1587.30 e. 1730.16 f. None of the other options
