Final answer:
The cost of reducing pollution to the desired levels for both pickle factories is $16,000.
Step-by-step explanation:
To reduce pollution to the desired levels, each pickle factory needs to reduce its emissions from 20 tons to 10 tons per year. 'Crunchy Ponds Pickles' can clean the pollution at a cost of $500 per ton, while 'Sweet Rose Pickles' can clean it at a cost of $1,100 per ton. Therefore, the cost of reducing pollution to the desired levels for each factory is as follows:
'Crunchy Ponds pickles': $500/ton x (20 tons - 10 tons) = $5,000
'Sweet Rose pickles': $1,100/ton x (20 tons - 10 tons) = $11,000
The total cost of reducing pollution to the desired levels for both factories is $5,000 + $11,000 = $16,000.
