The new england cheese company produces two cheese spreads by blending mild cheddar cheese with extra sharp cheddar cheese. the cheese spreads are packaged in 12-ounce containers, which are then sold to distributors throughout the northeast. the regular blend contains 80% mild cheddar and 20% extra sharp, and the zesty blend contains 60% mild cheddar and 40% extra sharp. this year, a local dairy cooperative offered to provide up to 8100 pounds of mild cheddar cheese for $1.20 per pound and up to 3000 pounds of extra sharp cheddar cheese for $1.40 per pound. the cost to blend and package the cheese spreads, excluding the cost of the cheese, is $0.20 per container. if each container of regular is sold for $1.95 and each container of zesty is sold for $2.20, how many containers of regular and zesty should new england cheese produce?
