In 2 hours, Scott can read 15 pages of spanish literature.

a. what is Scott's opportunity cost of reading 30 pages of literature?

To find Scott's opportunity cost of reading 30 pages of literature, we need to understand what an opportunity cost is. Opportunity cost refers to the value of the next best alternative forgone when making a decision.

In this case, the next best alternative to reading 30 pages of literature is not reading those pages and doing something else with that time. Since we know that Scott can read 15 pages of literature in 2 hours, we can calculate the time it would take him to read 30 pages by setting up a ratio:

15 pages / 2 hours = 30 pages / x hours

Cross-multiplying the ratios, we get:

15x = 60
x = 60 / 15
x = 4

Therefore, it would take Scott 4 hours to read 30 pages of literature. So, his opportunity cost of reading 30 pages of literature is the alternative he is giving up: 4 hours of time that he could have spent doing something else.
