example 3 Peanut Production Chapter 4.2 Georgia’s production of peanuts has increased moderately in the last 10 years, but profit margins have been reduced by lower prices, declining yields, and increasing costs. The table gives the annual revenue, variable costs, and fixed costs for peanut production in Georgia for the years 1998–2002. 19981999200020012002 Revenue ($) 57,25058,39559,56360,75461,969 Variable Costs ($) 28,06428,90529,77330,66631,586 Fixed Costs ($) 11,38211,72412,07612,43812,811 The function that models the revenue from peanut production in Georgia for the years 1998–2002 is given by where x is number of years after 1990. The function that models the total cost (variable plus fixed) of peanut production in Georgia is given by where x is the number of years after 1990. 2009 PBLPathways
