Answer:
The 10% off sale will save Melissa $10.49.
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:
[tex](195.99-5\%\ of\ 195.99)[/tex]
[tex]=(195.99-\frac{5}{100}\times 195.99)[/tex]
[tex]=(195.99-9.80)[/tex]
[tex]=186.19[/tex]
Now, adding the sales tax:
[tex]186.19+7\%\ of\ 186.19[/tex]
[tex]=186.19+\frac{7}{100} \times 186.19[/tex]
[tex]=186.19+13.03[/tex]
[tex]=199.22[/tex]
Thus, the price is $199.22.
Now, to get the price of 10% off sale:
[tex]195.99-10\%\ of\ 195.99[/tex]
[tex]=195.99-\frac{10}{100} \times 195.99[/tex]
[tex]=176.39[/tex]
So, adding sales tax:
[tex]176.39+7\%\ of\ 176.39[/tex]
[tex]=176.39+\frac{7}{100} \times 176.39[/tex]
[tex]=188.73[/tex]
Hence, the price is $188.73.
Now, to get the money 10% off sale will save Melissa:
[tex]199.22-188.73[/tex]
[tex]=10.49[/tex]
Therefore, the 10% off sale will save Melissa $10.49.
