Answer :
We start by noting that the initial amount of water in the bucket is
[tex]$$3000 \text{ ml},$$[/tex]
and the leak causes the water to decrease by
[tex]$$18 \text{ ml per minute}.$$[/tex]
Let [tex]$x$[/tex] be the number of minutes that have elapsed. The decrease in water due to the leak after [tex]$x$[/tex] minutes is
[tex]$$18x \text{ ml}.$$[/tex]
Thus, the amount of water remaining in the bucket after [tex]$x$[/tex] minutes is given by subtracting the water lost from the initial amount:
[tex]$$ y = 3000 - 18x. $$[/tex]
For example, if we want to find the amount of water remaining after 15 minutes, substitute [tex]$x = 15$[/tex] into the equation:
[tex]$$
\begin{aligned}
y &= 3000 - 18(15) \\
&= 3000 - 270 \\
&= 2730.
\end{aligned}
$$[/tex]
So, after 15 minutes, there would be [tex]$2730$[/tex] milliliters of water remaining in the bucket.
To summarize:
- The function describing the remaining water is [tex]$$y = 3000 - 18x.$$[/tex]
- After 15 minutes, [tex]$$y = 2730 \text{ ml}.$$[/tex]
[tex]$$3000 \text{ ml},$$[/tex]
and the leak causes the water to decrease by
[tex]$$18 \text{ ml per minute}.$$[/tex]
