Assume a company makes only three products, A$,$ B$,$ and C:

Product A Product B Product C

Estimated customer demand in units $700600800$

Selling price per unit $ $80$ $ $65$ $ $45$

Variable cost per unit $ $35$ $ $26$ $ $20$

Machine$-$hours per unit $2\mathrm{.}53\mathrm{.}01\mathrm{.}25$

The company has only $3,400$ machine$-$hours available. What is the highest total contribution margin that the company can earn if it makes optimal use of its constrained resource?
