Question

Carleen bought 3 gallons of milk for $12. how much would 4 gallons of milk cost​

Answer 1

You can set this up in an algebraic expression which would be 3/12=4/x. The next step to this is cross multiplying which you would have to do 3(x), and 4(12). It should then look like 3x=48, then you would need to divide both sides by 3, when that is finished x should equal 16. The answer would be $16 for 4 gallons of milk.

I really hope that helped you!

Answer 2

16

Explanation:

ok so if 3×4=12 the you add four at the end cause it's repaying but anyway 12+4=16 I think don't come after me
