Answer 1

The rate of change on the graph is 2 which represents Elizabeth's cost for 1 ton of coffee beans.

Explanation:

Rate of change is calculated using the formula
`(y_(2) -y_(1) )/(x_(2) -x_(1) )`.

Taking two points from the graph, we can calculate the rate of change.

The two points I've chosen are (0,60) and (10,80).

That means that
`x_(1) = 0, y_(1) = 60, x_(2) = 10,` and
`y_(2) = 80`.

Now, plugging these numbers into the formula we get:

`(80-60)/(10-0)`

Which simplifies to:

`(20)/(10) = 2`

Therefore, the rate of change on the graph is 2.

This represents Elizabeth's cost for 1 ton of coffee beans as the y-axis is labeled cost, and the x-axis is labeled coffee beans purchased. Therefore, 2 represents the cost of coffee beans, or the cost for 1 ton of coffee beans.
