Answer:
220%
Step-by-step explanation:
[tex]Percentage\ Increase/Decrease=\frac{Final\ Quantity\ - Initial\ Quantity}{Initial\ Quantity} *100\\Percentage\ Increase/Decrease=\frac{16-5}{5}*100\\=11*20\\=220\ \%[/tex]
As Final quantity is larger than the Initial Quantity, the net percent is an increase.
