Final price of the coffee table is $98.9.

Step-by-step explanation:

Original price of a coffee table = $115

Discount on a coffee table = 20%

So, After discount, it becomes,

$\text{ Price}=\frac{100-20}{100}\times 115\\\\\text{ Price}=\frac{80}{100}\times 115\\\\\text{ Price}=0.8\times 115\\\\\text{ Price}=\$92$

Rate of sales tax = 7.5%

So, after tax the price becomes,

$\text{ Price}=\frac{100+7.5}{100}\times 92\\\\\text{ Price}=\frac{107.5}{100}\times 92\\\\\text{ Price}=\$98.9$

Hence, final price of the coffee table is $98.9.
