A new video game is expected to sell 100 copies the first hour at a local game store. After that, the sales will follow the function s(x) = 12(x − 1) where x is the number of hours. What is the function that shows total sales, including the first hour?
s(x) = 12(x − 1) − 100
s(x) = 100x − 12
s(x) = 100 − 12(x − 1)
s(x) = 100 + 12(x − 1)
