Answer 1

To find the total points Jack earned for his team, subtract the fine from the initial points he earned. Jack earned 15 points and was fined 3 1/2 points. The total points Jack earned for his team is 11.5 points.

Step-by-step explanation:

To find the total points that Jack earned for his team, we need to subtract the fine from the initial points he earned. Jack earned 15 points, and then he was fined 3 1/2 points.

To subtract a mixed number, we need to convert it to an improper fraction. 3 1/2 is equal to 7/2.

So, the total points Jack earned for his team is 15 - 7/2 = 15 - 3.5 = 11.5 points.
