The top right is the answer!
Total wings = 2*(# of birds with 2 wings) +(# of birds with one wing) +(# of wings on critters that are not birds) +(# of wings not on critters)
Let x is the amount of $11 per pound coffee
then the equation will be,
11x + 3(30) = 5 (x + 30)
11x + 90 = 5x + 150
11x - 5x = 150 - 90
6x = 60
x = 10
So, $10 is the amount of $11 per coffee that should be added
