Question

A 9-foot piece of rope costs $38.88. What is the price per inch?

$

Answer 1

To calculate the price per inch of a 9-foot piece of rope that costs $38.88, we first need to convert the length from feet to inches.

Since 1 foot is equal to 12 inches, we can convert 9 feet to inches as follows:

\[
9 \text{ feet} \times 12 \text{ inches/foot} = 108 \text{ inches}
\]

Now, we need to find the price per inch by dividing the total cost by the total length in inches:

\[
\text{Price per inch} = \frac{\text{Total cost}}{\text{Total length (in inches)}}
\]
\[
\text{Price per inch} = \frac{38.88}{108}
\]

Now, let's perform the calculation:

\[
\text{Price per inch} = 0.36
\]

Thus, the price per inch is:

\[
\boxed{0.36}
\]
