Answer
This tells us that the per capita beef consumption was 64.14 pounds in 2004 (which is x=4 years after 2000).
Work Step by Step
We are given that the per capita consumption of all beef in the US is given by the function $C(x)=-.74x+67.1$, where x is the number of years since 2000.
$C(4)=-.74\times4+67.1=64.14$ pounds
