theres no multiple choice for this one.. so just explain the answer and the steps to how you got the answer please :) 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.

    Is the sales tax before or after the discount?

    I'm assuming after, so you would do y minus the 18% off, plus 8% of the discounted price.

    To calculate the discounted price, you would do the original price, y, minus 18% of y.

    Okay, so you have the item at the original price, y. Correct? Then it's on sale for 18% off. So you do 18% times y to get how much money off of the price. Then to find the actual discounted price, you do the original price minus the discount, which is \(y-(18\%)y\)

    Then, you have to add sales tax, which is 8%. So, you take that expression up there, multiply it by 8% to find the amount of the tax, which you then add to the expression to find the total amount paid.

    1. Find discount (amount off): (18%)y 2. Simplify: 0.18y You with me so far?

    3. Next, find the discounted price. Original Price - discount off = y - 0.18y Which equals what?

    I don't understand what you want...? Step 1: Find discount (amount off of original price)

    what i mean is to like not add the parentheses for example... dont do this: (amount off of original price) actually put the answer .. you get me?

    Okay....the parenthesis is just to further clarify. Sorry if it confused you. 1: Find discount - (18%)y 2: Simplify: 0.18y 3. Find discounted price - y - 0.18y 4: Simplify: 0.82y OK?
