17.973 L

16.764 L

18.762 L

23.733 L

After 13 minutes have past, there will be a volume of 18.762 L of punch.

Step-by-step explanation:

In this problem, we are asked to find the volume at 13 minutes. We are given this equation...

y = -2.485x + 51.067

We can use this equation to solve our problem. 13 represents our x-value so, we will plug 13 in for x in the equation above.

y = -2.485(13) + 51.067

Multiply -2.485 by 13.

y = -32.305 + 51.067

Now, add the numbers together.

y = 18.762

So, after 13 minutes have past, then the volume of the punch would be 18.762 L.

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.
