Answer:
PLAN A:
(120 * 0.39) + (40 * 0.19) + 20 = $74.40
PLAN B:
(120 * 0.49) + (40 * 0.14) + 20 = $84.40
PLAN C:
$20 + $75 = $95 ;
PLAN A is optimal from 0 to 192 minutes
PLAN C is optimal from 192 minutes onward ;
Explanation:
PLAN A :
Service charge = $20
Daytime = $0.39 per minute
Evening = $0.19 per minute
PLAN B :
Service charge = $20
Daytime = $0.49 per minute
Evening = $0.14 per minute
PLAN C :
Service charge = $20
225 minutes = $75
Minutes beyond 225 = $0.36 per minute
A.)
Determine the total charge under each plan for this case: 120 minutes of day calls and 40 minutes of evening calls in a month.
PLAN A:
(120 * 0.39) + (40 * 0.19) + 20 = $74.40
PLAN B:
(120 * 0.49) + (40 * 0.14) + 20 = $84.40
PLAN C:
$20 + $75 = $95
b. If the agent will use the service for daytime calls, over what range of call minutes will each plan be optimal?
PLAN A:
20 + 0.39D = 95
0.39D = 95 - 20
D = 75 / 0.39
D = 192.31
Answer:
c) a firm does not have sufficient time to change the level of use some of its inputs.
Explanation:
The definition of short-run in economics is not a term to be used for a specific certain period of time but it means that the period of time is too short that the firms cannot change the level they are using of some of their inputs or costs. It means they do have fixed costs they cannot change. For example, all machinery installed, a yearly rent paid, electricity or others that the firm cannot change unless there is sufficient time. In a short period of time, it will have those costs anyway. The firm cannot change the level of that input. And it is short run of at least one input. It may be many. But it is not necessary to have all inputs unchanged to consider that period of time as short-run.
However, firms can change level of inputs if they have more time. That is cost the long run. All costs are variable costs when we are in long run.
Answer: stability
Explanation: In simple words ,The probability that the origin of the attribution would change over a duration of time is called attribution. For instance, if a person decides to get such a big promotion, they might equate it to a lack of skill.
This suggests uncertainty, as the person must improve their skills and obtain an education in order to ultimately influence the outcome. It is not a sustainable situation, but one that can be modified by behavioral change.
Thus, from the above we can conclude that the correct option is D.

Explanation:
The answers would be:
Article 2 uses a scientific claim because the author says the Earth is in a cooling cycle.
Although Article 1 mentions evidence discovered by scientists, more research is needed about the data source to determine if the claim is scientific.
