Question

If a pen is $1.50 and there is 4% tax what would be the answer and also 19.99 with 2% tax

Answer 1

To calculate the total cost including tax, multiply the original price by the tax rate, and then add the result to the original price.

Step-by-step explanation:

To calculate the total cost including tax, multiply the original price by the tax rate, and then add the result to the original price.

For example: if a pen is $1.50 and there is a 4% tax, the tax amount would be $1.50 times 0.04 = $0.06. The total cost including tax would be $1.50 + $0.06 = $1.56.

Similarly, if an item is $19.99 and there is a 2% tax, the tax amount would be $19.99 times 0.02 = $0.3998 (rounded to $0.40). The total cost including tax would be $19.99 + $0.40 = $20.39.
