17 Doubling an Investment You have deposited $500 in an account that pays 6.75% interest, compounded continuously. How long will it take you money to double?

18 Average Salary for Public School Teachers For selected years from 1985 to 2004, the average salary y (in thousands of dollars) for public school teachers for the year t can be modeled by the equation y=-1.562 + 14.584 ln t, 5≤t≤24. where t =5 represents 1985. During which year did the average salary for public school teachers reach $44,000?
