The price of a calculator is $12.50. The sales tax is 7.5%. How much will you pay?
A. $13.40
B. $13.44***
C. $13.57
D. $13.61
Looks good to me.
To find out how much you will pay, you need to calculate the amount of sales tax and then add it to the original price of the calculator.
First, you need to find the amount of sales tax. To do this, multiply the original price of the calculator ($12.50) by the sales tax rate (7.5% expressed as a decimal).
$12.50 * 0.075 = $0.9375
So, the sales tax amount is $0.9375.
To find out how much you will pay in total, add the sales tax amount to the original price of the calculator:
$12.50 + $0.9375 = $13.4375
Rounding to two decimal places, you get $13.44.
Therefore, the correct answer is B. $13.44
