Nate’s mother wanted to buy some jewelry until she found out it was marked up 400%. if the original jewelry cost $100, what was the final price of the jewelry?

Turn 400% into decimal which is 4. If you know doctor pepper then u should already know how to turn deciaml into percent and percent into decimal.
Now, u multiple 4 times 100 which would give u 400 and then 400 plus the 100 which would give u 500
$500
Hope this help

Idon’t know what the answer is i wish i could
