N= 277
9×27 = 243
2×31 = 62
243+62 = 305
305-28=277

Answer:
$2.10
Step-by-step explanation:
Given: Regular price of vest is $15.99
Sales price of vest is $13.99
Sales tax= 5%
As given, there is difference in regular price and price on sales
∴ saving before tax= ![\$ 15.99 - \$ 13.99= \$ 2](https://tex.z-dn.net/?f=%5C%24%2015.99%20-%20%5C%24%2013.99%3D%20%5C%24%202)
saving before tax= $2
Now, applying tax on both price to look at the saving on vest.
Tax on regular price= ![5\%\ on\ \$ 15.99+ \$ 15.99](https://tex.z-dn.net/?f=5%5C%25%5C%20on%5C%20%5C%24%2015.99%2B%20%5C%24%2015.99)
⇒ Tax on regular price= ![0.7995+ 15.99= \$ 16.7895](https://tex.z-dn.net/?f=0.7995%2B%2015.99%3D%20%5C%24%2016.7895)
∴ Price of vest after applied on regular price=
.
Next Tax applied on discounted price of vest.
Tax applied on discounted price= ![5\% of \$ 13.99+ \$ 13.99](https://tex.z-dn.net/?f=5%5C%25%20of%20%5C%24%2013.99%2B%20%5C%24%2013.99)
⇒ Tax applied on discounted price= ![0.6995+ 13.99= \$ 14.6895](https://tex.z-dn.net/?f=0.6995%2B%2013.99%3D%20%5C%24%2014.6895)
Finding difference of price of vest to know the saving on sale.
Saving on vest= ![16.7895 - 14.7895= \$ 2.10](https://tex.z-dn.net/?f=16.7895%20-%2014.7895%3D%20%5C%24%202.10)
Hence, Saving on buying vest on sale is $2.10
