Question:

A swim team has won 24 out of 36 meets. The team still has 12 more meets in the season. How many of the remaining meets must the team win in order to win 70% of all meets entered during the season?

A 10
Explaination

The team has entered 36 meets in total and will enter 12 more. 36 + 12 = 48 70% of 48 = 0.7 x 48 = 33.6. We will round up to 34 since the team cannot win a portion of a meet. The team must win 34 meets, and it has already won 24 meets. Therefore, the team must win 34 - 24 = 10 meets.
