Step-by-step explanation:
Given:
The listed price of the camera is $195.99.
The camera is no sale for 10% off and Melissa has a coupon for 5% off the sales tax is 7%.
Now, to find the money Melissa will save of the 10% off sale.
So, to get the price of camera of the 5% off sale:
![(195.99-5\%\ of\ 195.99)](https://tex.z-dn.net/?f=%28195.99-5%5C%25%5C%20of%5C%20195.99%29)
![=(195.99-\frac{5}{100}\times 195.99)](https://tex.z-dn.net/?f=%3D%28195.99-%5Cfrac%7B5%7D%7B100%7D%5Ctimes%20195.99%29)
![=(195.99-9.80)](https://tex.z-dn.net/?f=%3D%28195.99-9.80%29)
![=186.19](https://tex.z-dn.net/?f=%3D186.19)
Now, adding the sales tax:
![186.19+7\%\ of\ 186.19](https://tex.z-dn.net/?f=186.19%2B7%5C%25%5C%20of%5C%20186.19)
![=186.19+\frac{7}{100} \times 186.19](https://tex.z-dn.net/?f=%3D186.19%2B%5Cfrac%7B7%7D%7B100%7D%20%5Ctimes%20186.19)
![=186.19+13.03](https://tex.z-dn.net/?f=%3D186.19%2B13.03)
![=199.22](https://tex.z-dn.net/?f=%3D199.22)
Thus, the price is $199.22.
Now, to get the price of 10% off sale:
![195.99-10\%\ of\ 195.99](https://tex.z-dn.net/?f=195.99-10%5C%25%5C%20of%5C%20195.99)
![=195.99-\frac{10}{100} \times 195.99](https://tex.z-dn.net/?f=%3D195.99-%5Cfrac%7B10%7D%7B100%7D%20%5Ctimes%20195.99)
![=176.39](https://tex.z-dn.net/?f=%3D176.39)
So, adding sales tax:
![176.39+7\%\ of\ 176.39](https://tex.z-dn.net/?f=176.39%2B7%5C%25%5C%20of%5C%20176.39)
![=176.39+\frac{7}{100} \times 176.39](https://tex.z-dn.net/?f=%3D176.39%2B%5Cfrac%7B7%7D%7B100%7D%20%5Ctimes%20176.39)
![=188.73](https://tex.z-dn.net/?f=%3D188.73)
Hence, the price is $188.73.
Now, to get the money 10% off sale will save Melissa:
![199.22-188.73](https://tex.z-dn.net/?f=199.22-188.73)
![=10.49](https://tex.z-dn.net/?f=%3D10.49)
Therefore, the 10% off sale will save Melissa $10.49.
