Emerson purchased a game that was on sale for 18% off. the sales tax in his county is 8%. let y represent the original price of the game. write an expression that can be used to determine the final cost of the game.
pleeease heelp mee im so stuck 22 points

I will use x for the original price of the game.

x = y * 0.82 * 1.08

* is the multiplication sign.

If something is 18% off, that means it has 82% value. To find this do 100-18 and you get 82.

So if you multiply the original price by 0.82 you get how much it costs when it is on sale.

Now, to add the tax you would multiply by 1.08. If you multiply something by 1 it stays the same, but if you multiply by 1.08 it adds 8% value to the item that is being purchased.
