Arguillo Inc. is a $5,000-$acre farm that produces two products: Zilla and Corma. Zilla sells for $$3\mathrm{.}50$ per bushel $($assume that a bushel weighs $60$ pounds$).$ Without further processing, Corma sells for $$30$ per ton $($a ton equals $2,000$ pounds$).$ If the Corma is processed further, it can be sold for $$45$ per ton. Total joint cost up to the split$-$off point was $$875,000.$ Arguillo produced $70$ bushels of Zilla and $1$ ton of Corma per acre. If all the Corma were processed further, separate costs would be $$50,000$
