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
"her students to put two spoonfuls of seawater into their containers"
We have then:
(2) * (5) = 10 mililiter
"he gives each of her 22 students a container"
Thus,
(22) * (10) = 220 mililiter
Therefore, they will remain:
(0.4 * 1000) - 220 = 400 - 220 = 180 milliliter
Answer:
There will be left 180 mililiter of seawater after all 22 students have filled their containers
Answer:
130 is the answer
