Based on the data provided, you know that one shelf requires feet of lumber.

You can convert the Mixed number to Decimal number applying these steps:

1. You must divide the numerator of the fraction by the denominator.

2. You must add the result obtained to the Whole number part.

Then you get:

Knowing this, you can set up the following proportion:

Finally, you must solve for "x" in order to find its value. This is:

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

my answer is$ 12
