Answer: 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,
[tex]\text{ Price}=\frac{100-20}{100}\times 115\\\\\text{ Price}=\frac{80}{100}\times 115\\\\\text{ Price}=0.8\times 115\\\\\text{ Price}=\$92[/tex]
Rate of sales tax = 7.5%
So, after tax the price becomes,
[tex]\text{ Price}=\frac{100+7.5}{100}\times 92\\\\\text{ Price}=\frac{107.5}{100}\times 92\\\\\text{ Price}=\$98.9[/tex]
Hence, final price of the coffee table is $98.9.
