Select the correct answer. A basketball team played 15 games and won 80% of them. If the team expects to play 30 games in all, how many more games must it win to finish the season with a 90% winning percentage?
A.
12
B.
14
C.
15
D.
27

  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.

Additional comment

That means they must win every game of the last 15 played.

i think it's either c or d

step-by-step explanation: the entire question is extremely odd. 04 obviously refers to the interest rate. honestly i will say the answer is c. because the (2 x 12) part would mean it's compounded semiannually. i'll say choose c.

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
