You're feeling hungry so you order a 40-piece Chicken Nuggets from McDonalds. It costs $8.99. You have a 10% off coupon, but you also have to pay 10% sales tax. What is the final price? Round your answer to the nearest cent.

Respuesta :

In order to calculate the discount of 10%, we can just multiply the number by 90%, that is, 0.9.

And in order to calculate the increase of 10% by the taxes, we can multiply the number by 110%, that is, 1.1.

So, applying both these percentages together, we have:

[tex]\begin{gathered} \text{Price}=8.99\cdot0.9\cdot1.1 \\ \text{Price}=8.9 \end{gathered}[/tex]

So the final price will be $8.90.
