160 people join a new gym on the first day it opened 1/4 of the group joined becouse they received a discount on their membership. 3/8 of the group joined becouse they were advised to do so by a doctor. 1/5 of the group were motivated to join by watching olympics. a) what fraction of the group had some other reason for joining. b) how many people joined becouse they were advised to do so by a doctor. c) how many were motivated to join by watching olympics?

First, think of what you know. you know that the number t the end of the equation will need to be subtracted because it is the money he lost from buying the lawn mower. and your first two weeks have negative profit, so that tells you that c and d are wrong. now you can plug any of the weeks into a and b to see which one works. i'll start with plugging week 1 into a.this isn't right because it says your answer for week one should be -90.so now we need to try the same thing with b.this one got you the right answer, (sometimes if you only check with one of the weeks multiple will work so you need to check with more of the weeks, but it worked out fine here)this means that b is the correct answer.let me know if you need more clarification. i hope this : )
