Final answer:
The final price that the buyer will pay, after applying a promotion discount of 30% and a cash discount of 15%, is $119.75.
Step-by-step explanation:
To find the final price that the buyer will pay, we need to apply the discounts one by one. First, the promotion discount of 30% is applied to the suggested list price of $199.00. 30% of $199.00 is $59.70, so after the promotion discount, the price becomes $199.00 - $59.70 = $139.30.
Next, the cash discount of 15% is applied to the discounted price of $139.30. 15% of $139.30 is $20.895, which rounds up to $20.90. So after the cash discount, the final price the buyer will pay is $139.30 - $20.90 = $118.40.
Therefore, the correct answer is c) $119.75.
