The rate of change in the annual per capita consumption of chicken between 1995 and 2009 has the following model, shown above
R( t ) = `0.015 t^3 - 0.226 t^2 + 0.985 t - 0.469` where t is the number of years after 1995.
Interpret `int_0^14 ( 0.015 t^3 - 0.226 t^2 + 0.985 t - 0.469 ) dt ` = 27.31.

At the end of 14, on average, a person ate 27.31 pounds more chicken than at the end of 1995.
