Tables Question

If I have a table that I want some rows to include a 10% markup but other rows not, is there a formula that is able to help me determine this? Basically I have a Yes or No column currently, and what I would like, is any row that is marked "Yes" would automatically get the 10% markup while the rows marked "No" would  not get the markup. I'm not sure if it's possible or not, but figured I'd ask on here for some help before giving up. 

Thanks!
