To find the cost of 15 pencils, we need to find the cost per pencil and then multiply by 15.
The cost per pencil can be found by dividing the total cost of 6 pencils by the number of pencils, which is $3.72 / 6 = $0.62.
Now, we can multiply the cost per pencil by the number of pencils we want to find the total cost. $0.62 * 15 = $9.30.
Therefore, 15 pencils cost $9.30.
