A merchant wants to mix gummy worms worth $7 per pound and gummy bears worth $3 per pound to make 30 pounds of a mixture worth $4.60 per pound. How many pounds of each type of candy should he use?

Answer 1

If x lbs of worms, then

7x + 3(30-x) = 4.60*30

This is just like the interest problem, which is also a mixture problem.

Answer 2

How would I write out this problem to solve?

Answer 3

Huh? It's already written out. That's how I got the equation. Can you not solve the equation?

If you find x, that's how many lbs of worms you need. The rest (30-x) is bears.
