The store bought an IPad for $900 and sold it for $1200. What percentage was
the mark-up?

answer: The mark up percentage was 25% because if you find how much 900 is of 1200  which is 75% and subtract it by 100% which is 25%. To check your work you can multiply 25% *  1200 which equals 300 then add 300 to 900 which Equals 1200.

Just add the two numbers and it will give the answer 2100:
