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)

 s(x) = 100x − 12

 s(x) = 100 − 12(x − 1)

 s(x) = 100 + 12(x − 1)

now, you already know they have 100, which means it will be added, not multiplied or subtracted, so A and B are out.
