Techstreet.com is a small Web design business that provides services for two main types of websites: brochure sites and e-commerce sites. One package involves an up-front payment of $90,000 and monthly payments of 1.4 per "hit." A new CAD software company is considering the package. The company expects to have at least 6000 hits per month, and it hopes that 1.5% of the hits will result in a sale. If the average income from sales (after fees and expenses) is $150, what rate of return per month will the CAD soft- ware company realize if it uses the website for 2 years
