lianna [129]

Answer:

The 10% off sale will save Melissa <u>$10.49</u>.

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)

=(195.99-\frac{5}{100}\times 195.99)

=(195.99-9.80)

=186.19

Now, adding the sales tax:

186.19+7\%\ of\ 186.19

=186.19+\frac{7}{100} \times 186.19

=186.19+13.03

=199.22

Thus, the price is $199.22.

Now, to get the price of 10% off sale:

195.99-10\%\ of\ 195.99

=195.99-\frac{10}{100} \times 195.99

=176.39

So, adding sales tax:

176.39+7\%\ of\ 176.39

=176.39+\frac{7}{100} \times 176.39

=188.73

Hence, the price is $188.73.

Now, to get the money 10% off sale will save Melissa:

199.22-188.73

=10.49

Therefore, the 10% off sale will save Melissa $10.49.
