Mr. Davis wants to buy some oranges. He visits a local grocery store and finds that 6 oranges cost $2.
Write an equation that represents the relationship between the number of oranges, n, and their total cost, c. Express the rate of change in simplest form, if necessary.
C = (2/6)n = (1/3)n.
To write an equation representing the relationship between the number of oranges, n, and their total cost, c, we can use the given information: 6 oranges cost $2.
Let's define some variables:
n: number of oranges
c: total cost
We can observe that when n = 6, c = $2. This means that for every 6 oranges, the total cost is $2.
To represent this relationship in an equation, we can write:
c = (2/6) * n
In this equation, (2/6) represents the cost per orange, which is $2 divided by 6.
To express the rate of change in its simplest form, we can simplify the fraction:
c = (1/3) * n
So, the equation representing the relationship between the number of oranges, n, and their total cost, c, is c = (1/3) * n.
