For the answer to the question above
Retail price of steel-belted radial tire = $89.50 
Discount offered = 10% = $8.95 
Value before federal tax = $89.50 - $8.95 = $80.55 
Federal tax = 12%=$80.55(0.12) =$9.67 
Local sales tax = 5% =$80.55(0.05)=$4.03 
Selling price = $80.55 +$9.67+$4.03 =$94.25
I hope my answer helped you. Feel free to ask more questions. Have a nice day!
