Answer: Total cost of an item is $12.96.
Step-by-step explanation:
Since we have given that
Selling price of an item = $12
Rate of sales tax in one town = 8%
Since the equation of total cost of an item is written as
[tex]c+0.08c\\\\=c(1+0.08)[/tex]
So, we will put c = $12 to get the required answer:
[tex]Total\ cost=12(1+0.08)\\\\Total\ cost=12\times 1.08\\\\Total\ cost=\$12.96[/tex]
Hence, Total cost of an item is $12.96.
