Answer:
$1,383.53
Step-by-step explanation:
Given: The total number bricks required to make the wall= 830
The speed of crew= 300 bricks/hour
Total hours they take to make the wall= 830/300 Hour
The cost of labour =$4,000 per eight-hour
⇒The cost of labour for 1 hour = $4000/8 = $500
Now, the cost of wall= 830/300 x 500 = 1383.53
Hence, $1383.53 is the right answer, the cost of the new wall= $1383.53
