To find the cost of 65 pencils, let's first determine the cost of one pencil.
The cost for 7 pencils is $1.47, so the cost of one pencil is:
\[
\text{Cost of one pencil} = \frac{1.47}{7} = 0.21
\]
Now, to find the cost of 65 pencils:
\[
\text{Cost of 65 pencils} = 65 \times 0.21 = 13.65
\]
Thus, the cost to buy 65 pencils is:
**A. $13.65**
