thank you for the points back. I appreciate it
Answer:
Fixed costs are high, variable costs are low
Explanation:
The reason is that the fixed costs are high because these fixed costs are uncontrollable and their might not be an alternative which means we have to move with higher fixed costs. And this is because most of tasks in manufacturing are handled by the machines not humans. So the cost of maintenance, depreciation, etc are fixed costs which are uncontrollable.
Furthermore, the company has very small variable costs because the company enjoys economies of scales, fast paced manufacturing machines, etc. And this is controllable by investments in another more robust machinery.
The question is incomplete. The complete question is :
The Jackson family is undecided about whether or not to buy a new car. If the probability is .9 that they will buy one, and if the probability is .3 that they will buy a Ford, and if the probability is .4 that they will purchase a car getting more than 20 miles per gallon, what is the probability that they will buy either a car getting more than 20 miles per gallon or a Ford, if all Fords get more than 20 miles per gallon?
Solution :
Given that :
The probability of buying a new car, 
Probability of buying Ford = 0.3
That is, if Jackson family buy a car that is a ford car, 
= 0.27
The probability for getting more than 20 miles per gallon = 0.4
That is if Jackson family buy a car that have more than 20 miles per gallon mileage, 
The conditions
All of the car have more than 20 miles per gallon mileage.
It means that buying a ford car is subset of getting more than 20 miles per gallon.

Therefore, the probability of buying a car either getting more than 20 miles per gallon or ford = 
Therefore,



= 0.36
Thus the probability that Jackson family is buying a car either getting more than 20 miles per gallon or ford is 0.36
