Question

The dollar mark up is 5.60 and my percent mark up coast is 102.26 what is the final coast an mark up percent?

Answer 1

So what you've got is this:
\[x+5.60 =102.60\]
Which means x = 97.00

Now you find how much of a percentage markup $5.60 was on $97, so you do this:
\[$5.60/$97.00 = y\]

Move the decimal two places to the right, stick a "%" afterwards and you've got your percentage.
