Martha is preparing for exams in economics and sociology. She has time to read 40 pages of economics and 30 pages of sociology. In the same amount of time shecould also read 30 pages of economics and 60 pages of sociology.
Assuming that the number of pages per hour that she can read of either subjectdoes not depend on how she allocates her time, how many pages of sociology could she read if she decided to spend all of her time on sociology and none on economics?(Hint: You have two points on her budget line, so you should be able to determine the entire line.)
