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
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
