The description is a direction calculation.

{amount of peanuts}/{amount of mixture}={fraction as peanuts}

Let P = the percent peanuts.
highlight%28%289%2A55%2B6%2A40%29%2F%289%2B6%29=P%29

If you want an algebraic solution, you are free to assign variables to the other numbers in any way you want.
