$14.8 was the markup, And the price went up in 22%, how I got my answer!
I first found that adding $64+$14.8=$78.8, and for percentage, that took awhile. At first I thought that it would be 20% but upon further investigation I found that, 22% Of $64 is $14.8.
I hope this helps!
P.S. 20% of $64 is $12.8.
