Question is incomplete as the cost of the sidewalk is not given :
Assume the sidewalk cost an additional $6 per foot.
Answer:
$8366
Step-by-step explanation:
Given that :
Size of porch = 16 by 18 feets
Area of porch = (16 * 18) = 288 ft²
Cost per ft² = $27
Cost of porch = ($27 * 288) = $7,776
Sidewalk = 15feets
Cost per foot = $6
Cost of sidewalk = ($6 * 15) = $90
Cost of gate = $500
Total cost :
(cost of porch area + side walk + gate)
($7776 + $90 + $500) = $8366
Kindly note that the cost pwr foot of sidewalk was erroneously excluded and the value employed for the cost was only assumed.
