By using differential equations' concept, we get that there is no sugar in the beginning.
<h3>What is a differential equation?</h3>
A differential equation is an equation that connects the derivatives of one or more unknown functions.
Given:
Pure water = 2840 litres
sugar = 0.01kg per liter
Rate of sugar entering the tank = 4liter/min
New solution drains out at the rate = 4 litre/min
To find: sugar in the beginning.
Finding:
(a) In the beginning, the tank contains only pure water and no solution of water with sugar.
Hence, the sugar is null for t = 0.

What is between 2 and 2.5 is 2.25
A=P(1/2)^(t/h)
P=initial amount
t=time
h=half life
A=final amount
so
A=0.242188 grams
