Answer:
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...
<em>y = -2.485x + 51.067</em>
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.
