Subtract 2c from both sides
5c-25-2c=2c+6-2c
3c-25=6
add 25 to both sides
3c-25+25=6+25
3c=31
Divide both sides by 3
3c/3=31/3
c=31/3
hope this helps!

Answer:
$0.06 per square inch
Step-by-step explanation:
The question should be:
<em>"If tile costs $8.50 per square foot, how much does it cost per square inch?"</em>
<em />
To solve this, we basically need a conversion from feet to inches. BUT 2 times, since we are talking about "square feet" and "square inches".
We know 1 feet = 12 inches
Also, since we are going from square feet to square inches [big to small], we have to divide TWICE.
Thus, we will have:

We are dividing 8.5 (the cost) by 12, 2 times since we want square feet in square inches. The answer is:

So, tile costs $0.06 per square inch
