Find the linear equation that meets the stated criteria.The linear equation y = 227x + 6320 provides an approximation of the annual cost (in dollars) to rent an apartment at the Leisure Village Retirement Community, where x = 1 represents 1977, x = 2 represents 1978, and so on. Write an equation that yields the same y-values when the exact year number is entered.
A. y = 227(1977 - x) + 6320 B. y = 227(x - 1976) + 6320 C. y = 227(1976 - x) + 6320 D. y = 227(x - 1977) + 6320
