o 500 (generating het be l are taking two courses this semester, biology and chem- istry, You have quizzes coming up in both classes. The follow- ing table shows your grade on each quiz for different numbers of hours spent studying for each quiz. (For the purposes of this problem, assume that each hour of study time can't be subdivided.) For instance, the table implies that if you spent I hour on chemistry and 2 hours on biology, you would get a 4. )You 77 on the chemistry quiz and a 74 on the biology quiz. Hours of Study 0 Biology 60 68 74 78 Chemistry 70 82 3 85Explanation / Answer
Answer
SUPPOSE THERE IS ONLY 1 HOUR IN TOTAL TO STUDY
If I spend Zero Hours on studying chemistry then I will score 70 and If Istudy 1 hour on chemistry then I will score 77. Hence Increase in score = 7
If I spend Zero Hours on studying Biology then I will score 60 and If I study 1 hour on Biology then I will score 68. Hence Increase in score = 8. As marginal Increase in score is greater for Biology. Hence I will spend 1 Hour on Studying Biology and 0 Hours on Studying Chemistry
Answer = 1 hour on studying Biology and 0 hours on studying Chemistry
SUPPOSE THERE IS ONLY 2 HOUR IN TOTAL TO STUDY
If I spend Zero Hours on studying chemistry then I will score 70 and If Istudy 1 hour on chemistry then I will score 77. Hence Increase in score = 7
If I spend one Hours on studying Biology then I will score 68 and If I study 2 hour on Biology then I will score 74. Hence Increase in score = 6. As marginal Increase in score is greater for If i study 1 hour of Chemistry rather than 2 hours of Biology. Hence I will spend 1 Hour on Studying Biology and 1 Hours on Studying Chemistry.
Answer = 1 hour on studying Biology and 1 hours on studying Chemistry
SUPPOSE THERE IS ONLY 3 HOUR IN TOTAL TO STUDY
If I spend 1 Hours on studying chemistry then I will score 77 and If I study 2 hours on chemistry then I will score 82. Hence Increase in score = 5
If I spend one Hours on studying Biology then I will score 68 and If I study 2 hour on Biology then I will score 74. Hence Increase in score = 6. As marginal Increase in score is greater for If i study 2 hour of Biology rather than 2 hours of Chemistry. Hence I will spend 2 Hour on Studying Biology and 1 Hours on Studying Chemistry.
Answer = 2 hour on studying Biology and 1 hours on studying Chemistry
