Answer:
Option B.)34¢
Explanation:
we know that
To find out the unit rate divide the total cost by the number of rolls
In this problem the total cost is $3.99
The number of rolls is 12 (a dozen)
so
[tex]\frac{3.99}{12}=\$0.3325\ per\ roll[/tex]
Convert to cents
[tex]\$1=100c[/tex]
Divide by 100
33.25c
