The total amount Carla paid, we need to calculate the total cost of her purchases including sales tax.
First, let’s find the total cost of the items before tax:
Total cost before tax = Cost of hat + Cost of purse + Cost of dress
= $12 + $26 + $125
= $163
Next, let’s calculate the sales tax amount:
Sales tax amount = Total cost before tax * Sales tax rate
= $163 * 5.6%
= $9.128
Now, let’s add the sales tax amount to the total cost before tax to find the total amount paid:
Total amount paid = Total cost before tax + Sales tax amount
= $163 + $9.128
= $172.13
So, the total amount Carla paid is $172.13, which corresponds to option B.
