Solve the problem.In 1995, the average annual salary for elementary school teachers was $24, 269. In 2000, the average annual salary for elementary school teachers was $28,148. Let S be the average annual salary in the year x, where x = 0 represents the year 1995.a) Write a linear function that models the average annual salary for elementary school teachers in terms of year x.b) Use this function to determine the average annual salary for elementary school teachers in 2010.
A. a) S(x) = 770.8x - 24,269 b) $35,831.00 B. a) S(x) = 770.8x + 24,269 b) $35,831.00 C. a) S(x) = 775.8x - 24,269 b) $35,906.00 D. a) S(x) = 775.8x + 24,269 b) $35,906.00
