no.
I think I understand it. 
Apply the sale first then the tax.

So take off 13% from 100% , which will be 87%
so the price is (0.87y) and then let's add the tax, which is the 8% of the price after the 13% off., so tax is 0.08(0.87y)

In total you'll get: price + tax = 0.87 + 0.08(0.87y) or (1+0.08)(0.87y) 

therefore you're total cost is 1.08(0.87y)
