A chair's regular price is $349. It is on clearance for 30% off, and a costumer uses a 15% of coupon after that. What is the final cost of the chair before sales Tax?

$ 207.655

Step-by-step explanation:

Given that

Regular price = $349

Clearance = 30% off

Customer coupon = 15% off

Final cost of chair before sales tax.

Cost of chair after clearance deduction

= 349 × (100 - 30)%

= 349 × 70%

= 349 × 0.7

= $ 244.3

Cost of chair after coupon

= 244.3 × (100 - 15)%

= 244.3 × 85%

= 244.3 × 0.85

= $207.655

Thus, the cost of chair before sales tax = $207.655
