 Question 110213: A recreational softball team paid a league entry fee of \$825. The cost was covered by equal contributions from each memeber on the team. If there were four more team members, each person could contibute \$20 less. How many memebers does the team have? i tried to write an equation... i made "x" be the money the players were contributing and "p" be the number of players since it said the fee was split evenly, i put 825/x = p. also, i had (p+4) = 825/(x-20) because if there were four more players they would have to pay \$20 less than before. After that, i could understand how you were able to figure out how many members the team had. Could you help me please? Thanks a lot tutor! Click here to see answer by stanbon(57424)
