To make a particular component requires an overhead $($fixed$)$ cost of $$5000$ and a variable unit cost of $$6\mathrm{.}50$ per unit. What is the total cost and the average cost of producing a lot of $1000?$ If the selling price is $$15$ per unit, what is the break$-$even point?To make a particular component requires an overhead $($fixed$)$ cost of $$5000$ and a variable unit cost of $$6\mathrm{.}50$ per unit.
