An insurance company is offering two insurance policies to your business. The monthly premium for Policy A is
$50, and it gives $10,000 of theft insurance plus $180,000 in liability insurance. The monthly premium for
Policy B is $40, and it gives $15,000 of theft insurance plus $120,000 in liability insurance. If your business
needs at least $300,000 in theft insurance and $3,000,000 in liability coverage, how many units of each policy
should be purchased from the insurance company to minimize the monthly premium? What is the minimum
premium?
