vlookup formula that additioanlly calculates a % of a value


Column A sheet 1 has codes and corresponding prices in column B. Column A sheet 2 has the same codes but with different $$ (column B). Column C Sheet 1 should have a formula calculating what % of a new price is the old price. I assume it should be a v-lookup formula first to look up a code, but I am not sure how to add a % calculation after that.

Please see the attached file.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.
