Answer:
$306 = Cost of 1 square inch of the patching material in question.
$306 = 1 in²
Explanation:
The conversion factor is am expression that is used to prove the equivalence of some quantities with different units.
The conversion factor basically converts from one quantity to another.
For this question, the conversion factor given for the patching material is $306/in².
This means that the patching material costs $306 for every square inch, the equation for the conversion is thus
$306 = 1 in² of the patching material.
Hope this Helps!!!
