One machine will have total fixed costs of $$5,900$ per day, two machines will have total fixed costs of $$10,700$ per day. Variable costs are $$50$ per customer, revenue is $$130$ per customer.

$1.$ Determine the break$-$even point for one machine.

a$.74$ Customers per Day

b$.81$ Customers per Day

c$.106$ Customers per Day

$$

$2.$Determine the break$-$even point for two machines.

a$.196$ Customers per Day

b$.141$ Customers per Day

c$.134$ Customers per day
