Solve the problem.The linear equation y = 82.67x + 1181 provides an approximation of the value (in dollars) of an account opened on January 1, 2010, in the amount of $1181 and earning 7% simple interest, where  represents January 1, 2010, x = 1 represents January 1, 2011, x = 2 represents January 1, 2012, and so on. Write an equation that yields the same y-values when the exact year number is entered.

A. y = 82.67(2011 - x) + 1181 B. y = 82.67(2010 - x) + 1181 C. y = 82.67(x - 2010) + 1181 D. y = 82.67(x - 2011) + 1181
