You x all the sides together and add the 2 numbers you get
Answer:
no false.
Step-by-step explanation:
Given:
The formula for total cost is
![T=p+\dfrac{s}{100}p](https://tex.z-dn.net/?f=T%3Dp%2B%5Cdfrac%7Bs%7D%7B100%7Dp)
where, p is the price of item and s is the sales tax rate (as a percent).
You pay $14.77 for an item priced at $14.
To find:
The the tax rate.
Solution:
You pay $14.77 for an item priced at $14. So,
Total cost (T) = $14.77
Price of item (p) = $14
Putting T=14.77 and p=14 in given formula, we get
![14.77=14+\dfrac{s}{100}(14)](https://tex.z-dn.net/?f=14.77%3D14%2B%5Cdfrac%7Bs%7D%7B100%7D%2814%29)
![14.77-14=\dfrac{s}{100}(14)](https://tex.z-dn.net/?f=14.77-14%3D%5Cdfrac%7Bs%7D%7B100%7D%2814%29)
![0.77=\dfrac{s}{100}(14)](https://tex.z-dn.net/?f=0.77%3D%5Cdfrac%7Bs%7D%7B100%7D%2814%29)
Multiply both sides by 100.
![77=14s](https://tex.z-dn.net/?f=77%3D14s)
Divide both sides by 14.
![\dfrac{77}{14}=s](https://tex.z-dn.net/?f=%5Cdfrac%7B77%7D%7B14%7D%3Ds)
![5.5=s](https://tex.z-dn.net/?f=5.5%3Ds)
Therefore, the tax rate is 5.5%.
Answer:
option (c) 475
