Anew video game is expected to sell 130 copies the first hour at a local game store. after that, the sales will follow the function s(x) = 9(x − 1) where x is the number of hours. what is the function that shows total sales, including the first hour?
a) s(x) = 130 + 9(x − 1)
b) s(x) = 9(x − 1) − 130
c) s(x) = 130x − 9
d) s(x) = 130 − 9(x − 1)

Step-by-step explanation:

Video games sold in first hour = 130

After the first hour the sales will follow the function:

Where x is the number of hours.

So, in x hours hours video games sold = 9(x-1)

So, total video games sold (including first hour) = 130+9(x-1)

Thus the function that shows total sales, including the first hour:

Hence Option A is correct :

the thermometer is precise but not accurate
