The company’s fixed costs are $15,600,000 (that is, $78,000 per service outlet).Instructions(a) Calculate the dollar amount of each type of service that the company must provide in order to break even.(b) The company has a desired net income of $52,000 per service outlet. What is the dollar amount of each type of service that must be performed by each service outlet to meet its target net income per outlet?

For Break Even Point

Oil Change:    $ 210,000

Brake repair:  $   90,000

For target profit

Oil Change:    $ 350,000

Brake repair:   $ 150,000

Explanation:

Now, we solve for

the target mix:

sales weight times contribution ratio

0.70 x 0.20 + 0.30 x 0.4 = 0.26

Now we solve the break even point for each service outlet:

Oil Change: 78,000 / 0.26 = 300,000 sales revenue

we multiply by the weight to know eahc type of serivce sales revenue

Oil Change:   $ 300,000 x 0.7 = $ 210,000

Brake repair:  $ 300,000 x 0.3 = $  90,000

Now we solve for target profit:

(78,000 + 52,000) / 0.26 = 500,000

Oil Change:   $ 500,000 x 0.7 = $ 350,000

Brake repair:  $ 500,000 x 0.3 = $ 150,000

the answer is "b.the increased supply will create a surplus. "

the essential thought behind price controls is straightforward - utilize the power of law to modify the equilibrium of a market. for instance, the legislature may choose that the steel business needs to survive, and in this way pass a law to set a value floor on steel. this implies all steel sold must offer at or over the floor value, which must be set over the equilibrium cost for it to have any impact. the switch could likewise happen - the administration can choose that steel is excessively costly and set a value roof underneath its equilibrium value, with the goal that all steel must be sold at or beneath that ceiling.
