Group of answer choices

Answer 1

We would have to get the sale 13% and \(13=\frac{13}{100}\)
So, \(13\%\ of\ y = \frac{13}{100}(y)\) Then
\(y-\frac{13}{100}(y)=\frac{87}{100}(y)=0.87y\) (we change the decimal to a fraction).
So now we have `0.87y` as the `price after discount`
Now, the problem says `The sales tax in his county is 8%` So, \(\frac{8}{100}(0.87y)=0.08(0.87y)\)
Price of the discount:
\(0.87y+0.08(0.87y)=1.08(0.87)y\)
