Part A:
Given that forty percent of the players on a soccer team are experienced players.
Then, the original ratio of experienced to total players is given by 40/100 = 4/10
Part B:
Given that the expression [tex] \frac{100(x+4)}{x+10} [/tex] represents the percent of experienced players on the team after the coach adds x experienced players.
Then, the final ratio of experienced to total players is given by:
[tex] \frac{\frac{100(x+4)}{x+10}}{100} =\frac{x+4}{x+10}[/tex]
Part C:
Given that there are 10 players on the team now, and that the coach adds x experienced player, then the number of players on the team now is given by:
10 + x.
