Question

5. A raincloud contains 2500 litres of water. The cloud is decreasing in size at
a rate of 4.3% per hour. Calculate the volume of water in the cloud in 8
hours time.

Answer 1

Answer:

Volume 1758.88 litres

Step-by-step explanation:

$P = 2500. \ r = 4.3\% = \frac{4.3}{100} = 0.043, t = 8\\\\Volume = P(1 - r)^t$

            $= 2500(1-0.043)^8\\\\= 2500 \times 0.70355\\\\= 1758.88 \ litres$
