Answer:
8.48%
Step-by-step explanation:
Given that,
The estimated bill = $480
Actual costing of the bill = $524.50
We need to find the percent error in the bill. It can be calculated as follows :
![\%=\dfrac{524.50-480}{524.50}\times 100\\\\\%=8.48\%](https://tex.z-dn.net/?f=%5C%25%3D%5Cdfrac%7B524.50-480%7D%7B524.50%7D%5Ctimes%20100%5C%5C%5C%5C%5C%25%3D8.48%5C%25)
So, the percentage error in the bill is 8.48%.

![3m+21=6m](https://tex.z-dn.net/?f=3m%2B21%3D6m)
Solve for m.
Subtract 3m from both sides.
![21=3m](https://tex.z-dn.net/?f=21%3D3m)
Divide both sides by 3.
![7=m](https://tex.z-dn.net/?f=7%3Dm)
Calculate
.
![RA=3m+21+6m](https://tex.z-dn.net/?f=RA%3D3m%2B21%2B6m)
![RA=9m+21](https://tex.z-dn.net/?f=RA%3D9m%2B21)
Put m = 7.
![RA=9(7)+21](https://tex.z-dn.net/?f=RA%3D9%287%29%2B21)
