Here is an excel file that contains part of the responses from a class questionnaire. Using this data, select all correct options below.

Read the question carefully. Write the value of X that makes you indifferent between both options. In other words how much you should be offered in one year (value of X) so it will be as valuable to you as $100 now.	Read the question carefully. Write the value of X that makes you indifferent between both options. In other words how much you should be offered in 10 years (value of X) so it will be as valuable to you as $100 now.
