# Awater pail in your backyard has a small hole in it. You notice that it has drained a total of 3.5 liters in 4 days. What is the average change in water volume each day?

$0.875$ $\text{L/d}$

#### Explanation:

Well, we're given that the hole drains color(red)(3.5color(white)(l)"L" in color(green)(4color(white)(l)"d", so we can write the rate as

$\left(\textcolor{red}{3.5 \textcolor{w h i t e}{l} \text{L"))/(color(green)(4color(white)(l)"d}}\right)$

Now we perform this division, and afterward the denominator will be $1$ and thus it will tell us the number of liters drained per day:

$\left(\textcolor{red}{3.5 \textcolor{w h i t e}{l} \text{L"))/(color(green)(4color(white)(l)"d")) = color(blue)(ulbar(|stackrel(" ")(" "(0.875color(white)(l)"L")/(1color(white)(l)"d")" }} |\right)$

Therefore, color(blue)(0.875color(white)(l)"liters" are drained every day on average.
