The Nutty Professor sells cashews for $6.75 per pound and Brazil nuts for $5.00 per pound. How much of each type should be used to make a 50lb mixture that sells for $5.70 per pound?
c = lbs of cashews
b = lbs of brazil nuts
Are these the right equations?
b + c = 50
6.75b + 5c = 5.70
Thanks,

You are so close, or maybe it was just a typo.
Your last equation should have been
6.75b + 5c = 5.70(50)
when you solve, you should get b=20, c=30

Oh... thanks! Now I see why I got a past equation wrong.
Thanks for the help!
