Answer:

  C.  15

Step-by-step explanation:

The team has won ...

  0.80 × 15 = 12 . . . games

To finish the season with a 90% winning percentage, they must win a total of ...

  0.90 × 30 = 27 . . . games

That is, they must win ...

  27 -12 = 15 . . . more games

The team must win 15 more games to finish with a 90% win rate.
