Question

A balloon with a small leak loses 1% of its volume each day. If originally contains 24 liters of gas, what is the volume at the end of one week.

Answer 1

ANSWER

The volume at the end of one week will be 22.32 liters.

EXPLANATION

If the balloon with a small leak loses 1% of its volume each day, then by the end of one week, it will lose 7℅ of its volume.


If the balloon originally contains 24 liters of gas, then this corresponds to 100%.

The volume at the end of one week will correspond to (100-7)%=93%


The volume at the end of one week is

$= \frac{93}{100} \times 24$


$= \frac{2232}{100}$
$= 22.32 \: liters$
