Coloma Copper Incorporated is able to produce $$640$ worth of copper from one ton of low$-$grade copper ore. Because of its higher copper content, Coloma can produce $$940$ worth of copper from one ton of high$-$grade copper ore. Assuming Coloma currently has $5,000$ tons of high$-$grade ore, and a mining company is offering to trade Coloma $7,250$ tons of low$-$grade copper ore for $5,000$ tons of high$-$grade copper ore. What do you suggest Coloma to do$?$
