Question

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?

Answer 1

`0.875` `"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

`(color(red)(3.5color(white)(l)"L"))/(color(green)(4color(white)(l)"d"))`

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:

`(color(red)(3.5color(white)(l)"L"))/(color(green)(4color(white)(l)"d")) = color(blue)(ulbar(|stackrel(" ")(" "(0.875color(white)(l)"L")/(1color(white)(l)"d")" ")|)`

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