P membership fee for new members
nr number of new members
Normal annual fee of 300 to be reduced to 200
So the normal fee 200
Now for each increments above 60 members the annual charge will be reduced by 2
In case of less than 60 members the charge will be normal
So the expression will be;
P
200 for normal fee subtracted with 2 reduction of each increment above 60 multiplied by nr number of new members subtracted with 60 number of increment of members so it will be
P 200 2 nr 60
