The average consumption of milk m in gallons per person per

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 munber of years after 1997. Predict the consumption of milk in the year 2008.

Solution

m= -0.13t+8

2008 is 11 years after 1997, so substitute 11 for t

m= -0.13(11)+8

m=6.57 gallons
