If an employer does not offer a retirement plan, the best option that an employee can do is to invest in an insurance company that can offer such service. There are insurance companies that not only guarantee a person's investment on health, travel, and recreation, there are also those that give opportunities for people who are seeking to retire from their work.
Answer:
-$28.8.
Explanation:
Note, we were told,
- to assume the cost of a therm is $0.30
- the family uses 600 therms of energy annually.
<u>Savings on old furnace:</u>
- 600 * $0.30 * 0.80 (or written as 80%) = $144
<u>Savings on new furnace:</u>
- 600 * $0.30 * 0.96 (or written as 96%) = $172.8
Difference: $144 - $172.8 = -$28.8.
The question is incomplete. The complete question is :
A manufacturer believes that the cost function : 
approximates the dollar cost of producing x units of a product. The manu- facturer believes it cannot make a profit when the marginal cost goes beyond $210. What is the most units the manufacturer can produce and still make a profit? What is the total cost at this level of production?
Solution :
Given the cost function is :
Now, Marginal cost = 
So, if the marginal cost = $ 210, then the manufacturer also makes a profit and if it goes beyond $ 210 than the manufacturer cannot make a profit.
Therefore, we have to equate : 
So when x = 45, then C(x) = $ 8042.5
Therefore, the manufacturer 
to 45 units and 
This leads to a total cost of $ 8042.5
