Answer:
1 hour working on problems, 3 hours reading
Explanation:
the question is not complete:
Bob is a hard-working college freshman. One Tuesday, he decides to work nonstop until he has answered 200 practice problems for his chemistry course. He starts work at 8:00 AM and uses a table to keep track of his progress throughout the day. He notices that as he gets tired, it takes him longer to solve each problem.
Time Total Problems Answered Marginal gain
8:00 AM 0
9:00 AM 80 80
10:00 AM 140 60
11:00 AM 180 40
Noon 200 20
Since Bob's is able to answer more than 70 questions per hours only during one hour (from 8 to 9 AM), he can benefit more from reading the next 3 hours. Reading would be equivalent to answering 210 questions, while Bob was only able to answer 120 more questions in the following 3 hours.

120 = 2,400 / n
n = 20
Answer:
It would take exactly 37 years
Explanation:
If we suppose that the economy starts at 10,000 billion dollars in 2020, the economy would only double by the year 2057, reaching a value of 20,399 billion dollars.
If we substract 2020 from 2057, we obtain 37, which is the number of years it took for this economy to double growing at a rate of 2% per year.
Answer:
The correct answer is letter "A": economists include opportunity cost in zero economic profit, while accountants do not include opportunity cost in zero profit.
Explanation:
Normal profit is an economic term that means zero economic profits. To an economist, this is normal since total revenue equals total cost which includes both explicit and implicit costs. It differs from the accounting profit or zero profits since the latter does not take into consideration implicit cost.
