Decline in beef consumption. Annual consumption of beef per person was about 64.6 lb in 2000 and about 61.2 lb in 2008. Assuming that
the annual beef consumption t years after 2000, is decreasing according to the exponential decay model:
a. Find the value of k, and write the equation.
b. Estimate the consumption of beef in 2015.
