Angelina already had $1500 saved before she started. She isn't working while she's in school, so she can only save $250 a year each year she is in college. Ray didn't have any money saved before he started, but he has a part-time job. He figures that he can save about $750 a year each year that he is in college. Let x represent the number of years the two students are in college. Assume that this is the same number of years for both. Let y represent the total amount of savings in dollars after x years. What is the equation that represents Angelina’s savings for college? What is the equation that represents Ray’s savings for college? When will Angelina and Ray have the same amount saved for college? Explain how you know. After the first two years, who has the most saved? Explain how you know.

A farmer wants to fence in a rectangular plot of land adjacent to the south wall of his barn. No fencing is needed along the barn, and the fencing along the east side of the plot is shared with a neighbor who will evenly split the cost of that portion of the fence. Fencing costs $30 per linear foot to install and the farmer only wants to spend $9000. Let x be the length of fence that's shared with the neighbor. Find a formula for the area A(x) enclosed by the fence and the barn. What is the maximum possible area enclosed?
You want to estimate how many fish there are in a small pond. Let's suppose that you first capture n1=500 fish, tag them, and throw them back into the pond. After a couple of days you go back to the pond and capture n2=120 fish, of which k=30 are tagged. Estimate the number of fish in the pond. There are approximately Answer fish in the pond.
