Hey You! 
Let's solve this step-by-step: 
9.99 * 20% = 1.998
9.99 - 1.998 = 7.992
7.992 * 6.75% = 0.53946
7.992 + 0.53946 = 8.53746
The total cost of his order is $8.53
        
             
        
        
        
Hi there! I can help you with these! For these types of questions, all you have to do is that if there is a markup, multiply by one hundred something to get the new price, because you're including the original price and the markup. For example, if there is a 75% markup on something, you multiply by 175% (1.75). Or, if there is a markdown, basically multiply by the remaining percentage. For example, if the markdown is 35%, you multiply the original price by 65% (0.65), because that is the amount of the price that it's on sale for. With that being said, if you do this correctly, here are the answers:
1. $54
2. $2.25
3. $90
Hopefully if you're talking about the markup or markdown from these prices, those are your answers.
