(a) In fall of 1990 there were 2 million cod in the North Atlantic. Every winter their population grows by 4%, and every summer ?shermen and women catch 0.07 million cod and then stop. About how many cod will there be in fall of 2020?
(b) If you need more practice. You have an account that has $10,000 in it in January 2016. Every year in April you lose 7% of whatever is in the account at the time for taxes. Every year in December, you add $1000 to the account. Assuming this pattern doesn’t change, how much money will you have in the account in January of 2025?
(c) If you need more practice. Repeat part (b), but switch “April” and “December”. In other words, now the $1000 is added in April, and the 7% loss is in December.
