harris has $20.92 to spend on video-
game rentals at a local video store. the
store charges $3.95 per video-game rental
plus an 8.125% tax. what is the
maximum number of video games that
harris can rent?

You need to figure out how much each video game actually costs after tax.  

First, we are going to figure out how much 8.125 % tax is on a 3.95 video game.  

To do this, you take the % tax and divide it by 100. So we will divide 8.125 by 100 to get 0.08125. This is the tax in decimal form.

Then you multiply the decimal form of the tax by the cost of the video game. This means we go 3.95 x 0.08125 = 0.3209375

This means the store charges an *extra* 0.32 dollars per video game.  

So a video game from this store really costs 3.95 + 0.32 = 4.2709375

Now, figure out how many video games Harris can buy. Divide 20.92 / 4.27 = 4.899 video games

Since Harris can't buy 0.899 of a video game, he will only be able to buy 4 games total.
