Answer 1

The volume of water in Eduardo's pool after he fills it for
`5 (1)/(4)` minutes is 205 liters.

What is the Volume of water in his pool?

To find the volume of water in Eduardo's pool after he fills it for
`5 (1)/(4)` minutes, you can substitute
`m = 5 (1)/(4)` into the given expression 100 + 20m.

Let's calculate:

Volume = 100 + 20 ×
`(5 (1)/(4))`

First, convert
`5 (1)/(4)` to an improper fraction:

`5 (1)/(4) = (20)/(4) + (1)/(4) = (21)/(4)`

Now substitute into the expression:

Volume = 100 + 20 × 21/4

To simplify, multiply 20 by 21/4:

Volume = 100 + 420/4

Now add the fractions:

Volume = 100 + 105

Volume = 205 liters.
