A new video game is expected to sell 102 copies the first hour at a local game store. After that, the sales will follow the function s(x) = 11(x − 1) where x is the number of hours. What is the function that shows total sales, including the first hour?
 a. s(x) = 102 - 11(x - 1)
 b. s(x) = 102 + 11(x - 1)
 c. s(x) = 11(x - 1) - 102
 d. s(x) = 102x - 11
