In speech class,you lose 3 points for every 30 seconds you go over the time limit. Your speech is 90 seconds over the time limit. What integer represents the change in your points?
I don't get it
90 is 3 x 30
Each 30 seconds costs you 3 points.
So, you lose 3x3 = 9 points
It's a bit confusing with all those 3's floating around.
(3points/30s) * 90s = 9 Points.
Thanks, I may not have seen this answer when I needed it. But the work you showed should help me on my test! Thank you, Steve!

To find the change in points, we need to first determine how many points are deducted for each second that the speech goes over the time limit. In this case, you lose 3 points for every 30 seconds over the time limit.
Therefore, we can calculate the points deducted per second by dividing 3 points by 30 seconds:
3 points / 30 seconds = 0.1 points/second
Next, we need to determine the total number of seconds the speech went over the time limit. It is mentioned in the question that the speech is 90 seconds over the time limit.
Now, we can multiply the number of seconds over the time limit by the points deducted per second to find the change in points:
90 seconds * 0.1 points/second = 9 points
The integer that represents the change in points is -9, since the points are deducted.
