Karim is ordering video games. Each game costs $39.99, and there is a $4.85 shipping charge per order. How much will it cost him to order any number of video games?

Given:

Cost of a game = $39.99

Shipping charge = $4.85

Let,

number of video games be "n"

Now,

total cost = (cost of each game * total no. of games) + shipping charge

= $39.99n + $4.85

So, you use the above equation to find the total cost of video games.
