Step-by-step explanation:

First we have to find the total cost of the pencil pouch including taxes:


\text{tax}=16\cdot(5)/(100)=16\cdot0.05=0.8

The tax is $0.80, so the total cost of the pencil pouch is $16.80.

The change is the difference between how much Alene pays and how much does the item cost:


20-16.80=3.20

Answer:

She will receive $3.20 back
