Question

You pay $4.19 for 1.39 lbs. How much will you pay for 2.25 lbs

Answer 1

4.19 / 1.39 = x / 2.25

Multiply both sides by 2.25:

4.19 * 2.25 / 1.39 = x

6.78 = x

 

So it will cost $6.78.

Answer 2

Set up a ratio.

4.19/1.39 = x/2.25

 

or take 4.19/1.39 = price per pound, then multiply by the new number of pounds.
