Answer:
$820
Step-by-step explanation:
If you have a coupon to save $2.50, we can calculate the price per square yard as follows:
$23 - $2.50 = $20.5
Then, we need to calculate the area of the dining room, so the area is equal to:
5 yd x 8 yd = 40 yd²
Finally, the cost is equal to:
40 yd² x $20.5 = $820
So, the answer is:
$820
