Choices

4/10
x+10
4
10
x+4/x+10

Answer 1

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
`(100(x+4))/(x+10)` 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:


`((100(x+4))/(x+10))/(100) =(x+4)/(x+10)`



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.
