Answer: This chart demonstrates that the marginal cost initially decreases as production increases.
Marginal Cost refers to the cost of producing an additional unit of a good. As production increases, marginal costs will initially decrease.
In the short run, factors of production like capital are fixed. Only labor is variable and varies with the number of units produced. Initially, employing more labor results in better productivity and help in decreasing the marginal costs. However, as more units of labor are employed, labor become less productive and the law of diminishing marginal returns sets in. Hence the marginal cost curve begins to rise.

Later, the teaching assistant in Kyoko's chemistry course gives her some advice. "Based on past experience," the teaching assistant says, "working on 30 problems raises a student's exam score by about the same amount as reading the textbook for 1 hour." For simplicity, assume students always cover the same number of pages during each hour they spend reading.
Given this information, in order to use her 4 hours of study time to get the best exam score possible, how many hours should she have spent working on problems, and how many should she have spent reading?
- 3 hours working on problems, 1 hour reading
Answer:
When Kyoko solves problems during 3 hours and reads for 1 hour, her learning utility is equivalent to 150 problems solved.
Explanation:
We are not given the information about what happens between 9:00 to 10:00 AM, so we can assume that their is no marginal gain from solving problems during that hour.
Kyoko will be able to solve 120 problems (= 80 + 40) during 8:00 to 11:00 AM. Apparently she will not be able to solve any other problems beyond 11:00 AM, so in order to maximize her learning utility she must find another activity that will help her raise her test scores.
She has 1 free hour and we know that reading for 1 hour is equal to solving 30 problems, so she could decide to do that (apparently is that or doing nothing).
When Kyoko solves problems during 3 hours and reads for 1 hour, her learning utility is equivalent to 150 problems solved.
Answer:
B. Do not obstruct fire doors and shutters.
Explanation:
In a fire situation, fire extinguishers must be accessible and doors and windows must be clear so that people can quickly evacuate the scene. This is recommended by firefighters and should be followed by everyone, as fires happen suddenly and adherence to instructions can save people's lives.
