The annual amount A (in billions of dollars) Americans spent on meals and

beverages purchased for the home for the years since 2000 can be modeled

by

A (C) - 286 + 880

where t represents the year, with t = 3 corresponding to 2003. Two different

tables of values for A (t) are given below. Use the tables to answer the

following questions.
