The expression 100 + 20m, gives the volume of water in Eduardo's pool (in liters) after Eduardo spends m minutes filling his poo

Fudgin [204]

Answer:

205 litres

Step-by-step explanation:

The expression that gives the volume of water in Eduardo's pool (in liters) is:

$100 + 20m$

where m is time, in minutes

After $5\frac{1}{4}$ minutes ( $\frac{21}{4}$ minutes), the volume is will be:

$100 + (20 * \frac{21}{4} )\\\\\\100 + (5 * 21)\\\\\\100 + 105$

= 205 litres

The volume of water in the poll will be 205 litres.
