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.
Combine like terms.
1w - 0.25w = 0.75w
Hope this helps!
