The football team in school decided to raise shs 3600 for a party. Each student was to contribute the same amount.
However before the contributions were made five members of the football team decided to transfer to other schools.
This meant that the remaining contributors had to pay more to meet the same target.
a) If the increase in contribution per student was shs 24. Taking the original number of footballers to be n
i) Give an expression for the initial amount that each should have contributed.
ii) Give an expression for the contribution after the transfer.
iii) Form an equation hence find the number of members in the football team originally
b) Calculate the percentage increase in the contribution per student caused by the transfer.
