Ground beef sells for $4.75 per kg and ground pork sells for $5.50 per kg. How many kg of ground pork should be mixed with 8 kg of ground beef to make a mixture that sells for $5.10 per kg?

I don't know how to set this up or anything. Please help!

  • Algebra -

    Let x=weight of ground pork in kg
    then 8-x=weight of ground beef.
    total weight = 8 kg
    5.50x + 4.75(8-x) = 5.10 * 8

    Solve for x.
