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/year. 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. What is the variable cost for the self-developed site option? a. None of the other options. b. 0.46 c. 2180 d. 4.01 e. 2.99 f. 3.21 g. 4.47
