Texas Governor Rick Perry promised to put hundreds of cameras on the Texas-Mexico border and broadcast the video over the Web so that anyone, anywhere could become a border patroller, helping root out border crime and illegal crossings. As part of that project, Texas secured a federal grant for $3 million that paid for 200 mobile cameras in strategic high-traffic areas. If the 200 cameras are considered to be equivalent to 20 border patrol agents, each with an annual salary of $75,000, what is the rate of return over a 3-year project period?
