Help with protein increase formula

HI All - brain dead this morning and would like some help producing a formula

have product which has 8.5% protein content, ie 8.5%

would like to raise this to 16%

have protein powder available which has 50% protein per gram.

Can anybody help as my workings just don't look right!!

I'm sure its starring me in the face - dammed maths!

many thanks.

What are the total grams used in your batch?

I had a diagram here but the copy and paste didn't work to well. Subtract 16 from 50, and 8.5 from 16. This gives you a ratio of 7.5 parts of 50% added to 34 parts of 8.5% to give you 41.5 parts at 16%. This is a Pearson Square that I used often -( http://www.ext.colos...tk/01618.html.)It is easy to change to % for the mix. Just divide total parts (41.5) into 100 to give you a multiplier of 2.41, use this against the parts needed of both,(34 and 7.5} and that should end up to 100 parts or 100%.
Hope you can follow this. Try the website, it is much clearer than my humble try before I remembered the name of the method.
