Question
(2) The annual net profit for a company, from 1995 to 2005, can be approximated by the model an
10e0.2n, n = 1, 2, 3, ., N, where an is the annual net profit in millions of dollars, and n represents
the year, with n =1 corresponding to 1995. Estimate the total net profit during this period.
(3) A deposit of 15 dollars is made at the beginning of each month, for a period of 5 years, in an account
that pays 0.9 % interest, compounded monthly. Find the balance in the account at the end of the 5
years.
(4) A deposit of 20 dollars is made every 3 months, for a period of 10 years, in an account that pays 1%
interest, compounded quarterly. Find the balance in the account at the end of the 10 years.
(5) A deposit of $500 can be made with two options: earn 2% interest, compounded quarterly for 3 years,
or earn 1.5%, compounded monthly for 3 years. Find the balance after 3 years of both options.
