Answer:
$0.06 per square inch
Step-by-step explanation:
The question should be:
"If tile costs $8.50 per square foot, how much does it cost per square inch?"
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:
[tex]\frac{8.5}{12*12}[/tex]
We are dividing 8.5 (the cost) by 12, 2 times since we want square feet in square inches. The answer is:
[tex]\frac{8.5}{12*12}=0.06[/tex]
So, tile costs $0.06 per square inch
