Hello! So the skateboard was mark up by 100%. This mean that the price of that item doubled. Let's find the new price after that. 37.10 * 2 is 74.2. That's $74.20 after markup. Ellen bought that skateboard with 5% tax. To find out the total amount she paid, multiply 74.2 by 105% (1.05). keep in mind that 100% represents the full price. 74.2 * 1.05 is 77.91. There. Ellen paid $77.91 for the skateboard.
