Solve the problem.The average price for a gallon of milk from 1990 to 2000 can be approximated by P(x) = .102(x - 1990) + 1.87, where x is the year. Evaluate P(1998) and interpret the result.
A. P(1998) = 1.95; the average price of a gallon of milk in 1998 was $1.95. B. P(1998) = 2.69; the average price of a gallon of milk in 1998 was $2.69. C. P(1998) = 2.69; the average price of a gallon of milk in 1998 was $2.69 more than in 1990. D. P(1998) = 2.78; the average price of a gallon of milk in 1998 was $2.78.
