Question

Willy Wonka® wants to mix gummy worms worth $3 per pound and gummy bears worth $1.50 per

pound to make 40 pounds of a mixture worth $1.95 per pound. How many pounds of each should

he use?

Answer 1

Willy will need 28 lbs of gummy bears and 12 lbs of gummy worms.

If you take 12 lbs of gummy worms at $3/lb you end up paying $36 for all the gummy worms

And then you take 28 lbs of gummy bears at $1.50/lb you end up paying $42 for all the bears

The total expense is then $78 for that mix

And since 12 lbs +28 lbs = 40 lbs

Now take your total expense and divide it by 40 (the total number of lbs) and you will end up with the price per lb. = 78/40= $1.95

ANSWER: The answer then is: 12 lbs of gummy worms and 28 lbs of gummy worms
