Based on the amount of drool generated, the cost of the plastics, and the disposal cost, the annual cost of the machine drool is $289,560.
This can be found as:
= Material cost of machine drool - Disposal cost
Material cost = (Machine drool generated per month x Number of months in year x Cost of each ton of drool)
Disposal cost = (Machine drool generated per month x Number of months x disposal charge)
Solving gives:
= (190 x 12 x 70) + (190 x 12 x 57)
= 159,600 + 129,960
= $289,560
