1. You are selling magic instant math pills. If you charge five dollars, you end up making
200 sales every week. Each dollar increase in price results in 50 fewer sales. Assuming
linearity, find the equation of the demand curve and graph it (with price in dollars on the
horizontal axis).
2. A population doubles every 10 years. Find the equation of the population using an
exponential model.
3. A population has annual growth of 12.5 %. Using an exponential model, estimate the
doubling time.
