Final answer:
To calculate the total amount of money a person will pay for cookies with a 5.5% sales tax rate, add the cost of the cookies to the sales tax amount.
Step-by-step explanation:
To calculate the total amount of money a person will pay for the cookies, we need to add the cost of the cookies plus the sales tax. Let's assume the cost of the cookies is $4.00. To find the sales tax, we multiply the cost of the cookies by the sales tax rate of 5.5%. 5.5% of $4.00 is $0.22. Therefore, the total amount of money a person will pay for the cookies is $4.00 + $0.22 = $4.22.
