Given that 5 pounds of rice at a store cost $6.50.
Then 1 pounds of rice at a store cost = $6.50/5= $1.3
So the equation for the cost can be written as:
C=1.3P just like we write equation y=mx
Now we have to graph the cost C, vs pounds of rice.
Variable for Pounds of rice is not given so let it be "P"
So let's make a table for number of pounds (P) and cost (C) the we can graph the points from that table to get the final graph.
Attached graph is the final graph.
Using proportions, it is found that the differential equation which describes the growth of the pigeon population is given by:
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, considering the initial population and the population one week later, the rate of growth is given by:
k = 9/6 = 1.5.
The standard differential equation for population growth is:
Hence:
