Final answer:
The total cost of the sweater after-tax is $52.92.
Step-by-step explanation:
The sales tax is 8%, which means that the price of the sweater will increase by 8%. To calculate the total cost of the sweater after-tax, we need to add the sales tax to the original price of the sweater.
First, we calculate the sales tax amount by multiplying the original price by the sales tax rate: 49 * 0.08 = 3.92.
Next, we add the sales tax amount to the original price to get the total cost of the sweater after-tax: 49 + 3.92 = $52.92.
