Given the data in the problem, we can calculate the cost of production for each bucket:
one bucket requires:
500 grams of plastic and one-half hour of direct labor.
The plastic costs $10.00 per 500 grams and the employees are paid $15.00 per hour.
Therefore, one bucket costs (material and labor):
$10.00 + $15.00 * (1/2 hour) = $17.50 per bucket plus (1.10 * $7.50) = $25.75
for 380 buckets :
$25.75 * 380 = $9785
This value only represents the cost of production of 380 buckets for the month of March.
