Final answer:
To find the total cost of the boots with sales tax, multiply the original price by the sales tax rate and add the result to the original price. In this case, the total cost of the boots is $71.74.
Step-by-step explanation:
To find the total cost of a product with sales tax, you will need to find the amount of sales tax first and then add it to the original price.
In this case, the sales tax rate is 5(1)/(2)%, so first convert it to a decimal by dividing it by 100: 5.5% = 0.055.
Then, multiply the sales tax rate by the original price of the boots to find the amount of sales tax: $68 * 0.055 = $3.74.
Finally, add the sales tax to the original price to find the total cost: $68 + $3.74 = $71.74.
