Question

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

Answer 1

The answer is b. s(x) = 102 + 11(x - 1)

Answer 2

B s(x) = 102 + 11(x - 1)

This takes the first hour sales, 102, and adds the sales after that 11(x-1)
