Answer:

Required expression would be:

  • c(n) = 1680/n, where c(n) - is the contribution amount, n- number of contributors.

For different values of n we get:

  • c(10) = 1680/10 = 168
  • c(12) = 1680/12 = 140
  • c(14) = 1680/14 = 120
  • c(16) = 1680/16 = 105

Lets find f(n) formula

[tex]\boxed{\sf f(n)=\dfrac{1680}{n}}[/tex]

Now

[tex]\\ \sf\longmapsto f(10)=\dfrac{1680}{10}=168[/tex]

[tex]\\ \sf\longmapsto f(12)=\dfrac{1680}{12}=140[/tex]

[tex]\\ \sf\longmapsto f(16)=\dfrac{1680}{16}=105[/tex]

[tex]\\ \sf\longmapsto f(14)=\dfrac{1680}{14}=120[/tex]
