Answer:
it is D
Step-by-step explanation:
$810 ÷ 3 = 270 square feet
Area of the room is 270 square feet.
Area = 270 square feet, length = 18 feet
Area = Length x Width
270 = 18 x width
Width = 280 ÷ 18
Width = 15 feet
The room is 15 feet wide.
You first multiply $61 by .20(decimal form of 20%) and get $12.2
Since this is 20% off(that means it's less than the original price) so subtract 12.2 from $61=48.8
then add the tax so 48.8 by .05 =2.44
so 48.8+2.44
the final price is $51.24
