For this case, we look for the number of pencils per gram of rubber.

[tex]\frac {960} {5,376} = 0.178571428571[/tex]

0.178571428571 pencils per gram of rubber are made

We are looking for the number of pencils per hour.

[tex]0.178571428571 \frac {penc} {g} * 64,512 \frac {g} {h} = 11,520 \frac {pen} {h}[/tex]

Thus, 11,520 pencils per hour are made.
