Answer:
$207.655
Step-by-step explanation:
Firstly, we calculate the value taken off the cost by the clearance sales tag.
That would be 30/100 * 349 =104.7
We subtract this from the original = 349-104.7 = 244.3
Now, he applied a 15% coupon. That would be 15/100 * 244.3 = 36.645
The cost of the chair before sales tax = 244.3-36.645 = 207.655
