dollars, after n years. (4 points)
Part C: Holly wants to invest in an option that would help to increase her investment value by
the greatest amount in 20 years. Will there be any significant difference in the value of
Belinda’s investment after 20 years if she uses option 2 over option 1? Explain your answer by
showing the investment value after 20 years for each option. (4 points)
Part A:
Is Option 1 Linear or Exponential?
Is Option 2 Linear or Exponential?
