Respuesta :

The sweater would then cost (S x 1.085), with the 0.085 representing the tax value

Answer: Cost after tax is 1.085 times $S.

Step-by-step explanation:

Since we have given that

Price of a sweater be $S

Tax rate = 8.5%

Amount of tax is given by

[tex]\frac{8.5}{100}\times S\\\\=0.085\times S\\\\=0.085S[/tex]

So, Cost after tax will become

[tex]S+0.085S\\\\=1.085S[/tex]

Hence, Cost after tax is 1.085 times $S.
