A warehouse club allows non members to shop, but charges them a 10% mark up on all items purchased. If a computer costs $549.99 for members, what is the non member price?

    Ok, I'd start by changing 549.99 to 550$ A tad easier that way

    Ok, so the problem states that 550$ is the normal price, for members. If nonmembers are charged 10% more, that means they pay 110% total. Do you understand why?

    First, multiply the member price, 550$ by 10%

    Do you have a percent button? If not, you can also use .10 for 10%

    Ok, excellent! 55 is 10% of 550. So, if you add 55 to the original price of 550, you get the 10% markup, your final answer. Try that, I'll be back in a minute

    To cover his expenses, Denny marks the price of each item 30% more than his purchase price. What does Denny charge for items that cost him $1.04, $7.23, $9.99 and $42.77?

    Good. Now he's a little trick. 50% is .50, 85% is .85, and 100% is actually 1

    If you add your markup decimal (.30) to 1, you get 1.3 Right?

    Because the original price is 100% of itself, it's a bit complicated. Point is, if you take that 1.3 and multiply it by each of those prices, you get the correct answer
