Answer:
= $2,625
Step-by-step explanation:
Each time a bottle is added to the structure, It takes 30 minutes of labor at $7.50 per hour.
So the labor cost for adding one bottle to the structure is = 7.50 / 2
= $3.75 per bottle
The atisanal greenhouse requires 700 empty wine bottles to be embedded in a frame, so the total labor cost of the entire artisanal greenhouse would be,
= $3.75 x 700
= $2,625
