A trail mix contains peanuts, chocolate pieces, and raisins. There are twice as many raisins as chocolate pieces. There are 20 less peanuts than raisins. In total, the mix contains 200 trail mix pieces. Write an equation in terms of r (the number of raisins) to represent this situation.

I just need an equation then i can solve. Thank you!!!!!!

Let peanuts = p, chocolate = c and raisins = r
p = (r-20)
c = (r/2)
r = r
Equation is (r-20) + r/2 + r = 200
Take it home from here :) GL
