1. a store had 235 mp3 players in the month of january. every month, 30% of the mp3 players were sold and 50 new mp3 players were stocked in the store. which recursive function best represents the number of mp3 players in the store f(n) after n months? f(n) = 0.7 x f(n − 1) + 50, f(0) = 235, n > 0 f(n) = 237 − 0.7 x f(n − 1) + 50, f(0) = 235, n > 0 f(n) = 0.3 x f(n − 1) + 50, f(0) = 235, n > 0 f(n) = 237 + 0.7 x f(n − 1) + 50, f(0) = 235, n > 0 2. sophia invested some money in a bank at a fixed rate of interest compounded annually. the equation below shows the value of her investment after x years: f(x) = 500(1.05)x what was the average rate of change of the value of sophia's investment from the second year to the fourth year? 14.13 dollars per year 28.25 dollars per year 50.00 dollars per year 56.50 dollars per year
