To solve this problem, we can follow these steps:
a) Calculating the sales tax:
Sales tax = Price of the sweatshirt x Sales tax rate
Sales tax = $42.00 x 6%
Sales tax = $42.00 x 0.06
Sales tax = $2.52
Therefore, the amount charged for tax is $2.52.
b) Finding the total amount paid for the sweatshirt:
Total amount paid = Price of the sweatshirt + Sales tax
Total amount paid = $42.00 + $2.52
Total amount paid = $44.52
So, the total paid for the sweatshirt is $44.52.
