Ellen deposited $2,500 into a savings account
that earns 5% interest per year. her friend's
bank offers a 65 % annual interest rate. how

earned in one year if she had deposited her

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
