Final answer:
To find the total cost of an item with sales tax, multiply the original price by the sales tax rate and add it to the original price.
Step-by-step explanation:
To find the total cost of an item with sales tax, you need to add the sales tax amount to the original price of the item.
In this case, the sales tax is 4%. To calculate the sales tax, we multiply the original price by the sales tax rate: 56.75 * 0.04 = 2.27.
So the total cost of the item, including sales tax, is $56.75 + $2.27 = $59.02.
