Question

The average consumption of milk, m in gallons per person per year can be approximated by the equation m= -0.13t+ 8 where t is the number of years after 1997 Predict the consumption of milk in the year 2012 (Hint find the value of t that corresponds to the year 2012.) gallons

Answer 1

Given data:

The expression for the milk consuption is m= -0.13t+8.

For 2012, the value of t is 15, substitute 15 for t in the above expression.

$\begin{gathered} m=-0.13(15)+8 \\ =6.05\text{ gallons} \end{gathered}$
