please help with math

Answer:
The prices are the same when the package weighs 3 pounds.
Step-by-step explanation:
So basically we want to know when they're equal so we line up a equation like this:
$14+$2x=$20+$1.50x
We want to move over the x to one side of the equation.
2x-1.50x=20-14
Simplify
.5x=6
x=3
So the price is the same when the package weighs 3 pounds.
