Explanation:
First we have to find the total cost of the pencil pouch including taxes:
[tex]\text{tax}=16\cdot\frac{5}{100}=16\cdot0.05=0.8[/tex]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:
[tex]20-16.80=3.20[/tex]Answer:
She will receive $3.20 back
