Answer 6

\[(15+(15\times\frac{ 7 }{ 100 }))=\frac{ 321 }{ 20 }\]
\[\frac{ 321 }{ 20 }\times \frac{ 100-20 }{ 100 }=?\]
solve it @Samara8954

Answer 7

15 - 0.20(15) = the cost of the CD after the discount. So what did you get for this part of the problem ?

Answer 8

Now you would take the answer that you got and multiply it by .07....that is the tax that will be added.

Answer 9

Then you would take the answer you got for the first part of the problem, then add that to the answer you got for the second part of the problem and that will be the total.

Answer 10

The CD is $15.00
Less 20% = $15.00/100 x 20 = $3 i.e the CD is $12.00
sales tax@7% = $12 x 7/100 = 84/100 = $0.84
$12 - $0.;84 = $11.16
