Example 9 You have deposited $500 in an account that pays 6.75% interest, compounded continuously. How long will it take your money to double?
Example 10 For selected years from 1980 to 2000, the average salary y (in thousands of dollars) for public school teachers for the year t can be modeled by the equation where t = 10 represents 1980. During which year did the average salary for public school teachers reach $40,000?
