Answer:
2m / n² - 2n
Step-by-step explanation:
Given that:
Number of friends = n
Weekly rent = $m
To share rent fee equally :
Each friend will pay : $m / n
If 2 of the friend couldn't make the trip:
Additional amount to be shared by the others = 2(m/n) = 2m/n
Hence additional fee per friend who eventually made the trip:
Additional amount to be shared / number of friend who eventually made the trip
= (2m/n) ÷ (n - 2)
= 2m / n * 1 / n - 2
= 2m / n(n-2)
= 2m / n² - 2n
Let the money spent by John = y
and Amy=x
ATQ
x+y = $29
It is given that jon spend 5 more than Amy. SO he spend
x +5
x+y = $29
x+x+5=$29
2x = 29-5
2x= 24
x = 24/2 =12
So Amy spend $ 12 and Jon spend x+5 = 12+5 = $17
