a has p cups of peanuts and r cups of raisins
When she mixed the peanuts and raisins she made 12 cups of party mix
p + r = 12
that had twice as many peanuts as raisins how many cups of peanuts and
p = 2r
:
how many cups of raisins did linda have?
In the first equation replace p with 2r
2r + r = 12
3r = 12
r = 12/3
r = 4 cups of raisins
then obviously, 8 cups of peanuts
