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.
To find out how many miles does each person run, we can divide the total miles by 4 as each part is equal:
14÷4
=3.5miles
Each of them have to run 3.5 miles.
To prove the answer, we can multiply it by 4 to see if it is the original distance:
3.5 x 4
=14miles
Therefore 3.5 is the answer.
Hope it helps!
