    Sports radio stations numbered 220 in 1996. The number of sports radio stations has since increased by approximately 14.3% per year. Write an equation for the number of sports radio stations for t years after 1996. If the trend continues, predict the number of sports radio stations in 2015.

    Equation - where t is the number of years after 1996:
    R(t) = 220(1.143)^t

    We Want R(t) for 2015
    t = 2015 - 1996 = 19
    R(19) = 220(1.143)^19
    R(19) = 220 * 12.672969
    R(19) = 2788.05 ~ 2,788
