The population after 3 years would be 8.20 millions.
Step-by-step explanation:
Given,
Initial population = I = 4.2 million
Growing rate = r = 25%
If the initial population and growing rate is given, the formula to calculate the population (x) after n years would be:
By putting the values in the equation, we get
The population after 1st year (x1) would be
x1 = 5.25 million
Similarly,
x2 = 6.56 million
x3 = 8.20 million
Hence, the population after 3 years would be 8.20 millions.
But, if you are asking about the total population at that time. It would be
I + x1 + x2 + x3 = 24.21 million
<span>2 cups of flower equals 12 muffins, which means that (2/12) (cups of flower/muffins) times m muffins = cups of flowers. </span>
<span>On the second one, lets make an equation system. </span>
<span>Lets call this seasons score x. </span>
<span>Last season Betty scored 36 which is 8 less than twice the score this season. </span>
<span>Translating this to an equation yields the following expression: </span>
<span>2x - 8 = 36 </span>
<span>Then solving! </span>
<span>2x - 8 = 36 </span>
<span>2x = 44 </span>
<span>x = 22 </span>
