Two separate processes are being considered for manufacturing a product. Process A has fixed costs of $$12,000$ and variable

costs of $$6$ per unit. Process $B$ has fixed costs of $$16,000$ and variable costs of $$4$ per unit.

a$.$ What is the break$-$even quantity for the two processes $($Show your work$)?$

b$.$ Which process would be more cost$-$effective for producing $1,000$ units?

c$.$ Which process would be more cost$-$effective for producing $3,000$ units?
