Homework Help: Algebra

Posted by Valeria on Sunday, February 22, 2009 at 10:20am.

Here's my question:

Deep Thought Granola is 25% nuts and dried fruit. Oat Dream Granola is 10% nuts and dried fruit. How much of Deep Thought and how much of Oat Dream should be mixed to form a 20-lb batch of granola that is 19% nuts and dried fruit?

Here is a past question and the answer I got:

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 50-lb 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

What I am wondering is, since this problem is a little different because it is with percentages, not money amounts, do I still have to do what Reiny told me for the one equation?

For example, here are my 2 equations

x + y = 20
Is the second equation:
.25x + .10y = .19
Or is it:
.25x + .10y = .19(20)

Thanks,
