Question

Brenna rings up an item that costs $66. After sales tax, the total is $67.98. What is the sales tax percentage? Write your answer using a percent sign (%).

Answer 1

To calculate the sales tax percentage of an item that went from $66 to $67.98 after tax, subtract the original cost from the total to get the amount of sales tax paid ($1.98), then divide by the original price and multiply by 100 to get a 3% sales tax.

Step-by-step explanation:

The student is asking how to calculate the sales tax percentage based on the total cost of an item after tax compared to its original price before tax. In this case, we have an item that costs $66 and after sales tax, the total is $67.98.

To find the sales tax percentage, we'll need to follow these steps:

1. First, calculate the amount of sales tax paid by subtracting the original price of the item from the total price after tax. This gives us $67.98 - $66 = $1.98.
2. Next, divide the amount of sales tax by the original price of the item to get the rate of sales tax. Therefore, $1.98 ÷ $66 = 0.03.
3. Finally, convert the decimal to a percentage by multiplying by 100. So, 0.03 × 100 = 3%.

Therefore, the sales tax percentage is 3%.
