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 = n/3

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.

To write an equation that represents the relationship between the number of oranges, n, and their total cost, c, we need to determine the cost per orange.

We are given that 6 oranges cost $2. We can see that for every 6 oranges, the total cost is $2. Therefore, the cost per orange is $2 divided by 6, which is:

Cost per orange = $2 รท 6 = $0.33 (rounded to two decimal places)

Now, we can write the equation that represents the relationship between the number of oranges, n, and their total cost, c:

c = 0.33n

This equation states that the total cost, c, is equal to the cost per orange ($0.33) multiplied by the number of oranges, n.

The rate of change in this case is the cost per orange, which is $0.33.
