Solve the problem.The linear equation y = 229x + 6320 provides an approximation of the annual cost (in dollars) to rent an apartment at the Leisure Village Retirement Community, where x = 1 represents 2011, x = 2 represents 2012, and so on. Write an equation that yields the same y-values when the exact year number is entered.
A. y = 229(x - 2011) + 6320 B. y = 229(x - 2010) + 6320 C. y = 229(2011 - x) + 6320 D. y = 229(2010 - x) + 6320
