Final answer:
Without additional information, it is not possible to determine the exact amount of food Chisaka needs for each day she spacewalks or doesn't spacewalk, as we need more specifics to create an accurate inequality.
Step-by-step explanation:
To find out how much food Chisaka needs for each day that she spacewalks and for each day that she doesn't spacewalk, we need to formulate an inequality based on the information given. The inequality would look like As + Bn < 145, where A is the amount of food needed per day for spacewalking, B is the amount of food needed per day for non-spacewalking days, s is the number of spacewalking days, and n is the number of non-spacewalking days. However, without more information to create a specific inequality, such as the amount of food used for each activity or the specific number of days Chisaka will be doing each activity, we cannot determine the exact values for A and B.
