Walnuts sell for \$10 per pound and pecans for \$18 per pound. How much of each type of nut would produce 40 pounds of a mix that sells for \$15 per pound?

I would love to try that, but I have no idea where to begin. I don't have class until tomorrow night, so I cannot ask my instructor. I am not trying to be selfish with the help I've received from this site. I am grateful and I genuinely need help.

The best way to learn is to try to do these math problems. We all learn by trial and error and failing sometimes.

You know that you'll need more than half the mixture must be walnuts. There will probably be around 25 or so pounds of walnuts.

Let walnut w and pecan p
p = 40-w

10w + 18(40-w) = 40(15)

10w + 720 -18w = 600

-8w + 720 = 600

Solve for w
