Problem
	18.	Violet makes bracelets, which she sells. This year her bracelets sell for $8 each, but demand for them will drive the price up by $1 each year. a) Determine a formula for the price, P, of one of Violet’s bracelets in year x, where x = 0 represents this year. b) Use the model in part a) to predict the price of a bracelet 20 years from now. c)  Use the model in part a) to predict when the price of a bracelet will reach $25. d)  Create a graph of the model in part a). e)  Over what range of times does the model seem realistic? Explain.
