Question

shirts are 10% oft. The original price of one shirt is $12. What is the total cost in dollars, of 3 shirts at the sale price, including a 5% sales tax?*

Answer 1

Answer:

$34.02

Explanation:

10% off means that the price of the shirt is now 100% - 10% = 90%

The price of one shirt now is

$\frac{90}{100}\times12=10.8$

Furthermore, 5% sales tax means that the price will be 100% + 5% = 105% higher

The price of the shirt after tax will be

$\ 10.8\times\frac{105\%}{100\%}$
