A jewelry store bought a gold necklace and marked it up 110% from the original cost of $23.52. Later on, Dean purchased the gold necklace and paid 14.75% sales tax. How much, including tax, did he pay for the gold necklace?

When you mark something up, you add the original price and how much it was marked up. For example, if you marked something up 50%, the new price is (the original price + 50% of the original price).

 

Applying the same logic here, we have \(23.52 + (1.1 \times 23.52) \approx 49.40\). The 23.52 represents the original price, and the 1.1 x 23.52 represents how much it was marked up. 

 

The price after the mark up was \($49.40\). We now have to mark it up by \(14.75 \text{%}\)

 

Can you do this using the logic I just presented?

 

Feel free to ask if you need any help!!!
