A pet store is selling a new dog collar for $12.00. If there is a sales tax of 10%, what is the actual cost of the collar?
To calculate the actual cost of the dog collar with sales tax, we need to add the sales tax amount to the original price.
Step 1: Calculate the sales tax amount:
Sales Tax Amount = Original Price * Tax Rate
= $12.00 * 0.10
= $1.20
Step 2: Add the sales tax amount to the original price:
Actual Cost = Original Price + Sales Tax Amount
= $12.00 + $1.20
= $13.20
Therefore, the actual cost of the dog collar, including the 10% sales tax, is $13.20.
