Question

Please help me with number 2! I feel that I have the steps down I just need some clarification.

Answer 1

Given:

The table represents the number of students that buses can transport.

The objective is to find the constant rate of change.

Step-by-step explanation:

The general formula for rate of change is,

`\Delta r=(f(b)-f(a))/(b-a)`

Here, a represents the first value and b represents the successive value.

To find rate of change:

The rate of change can be calculated as,

`\begin{gathered} \Delta r=(216-144)/(3-2)=(72)/(1) \\ \Delta r=(288-216)/(4-3)=(72)/(1) \\ \Delta r=(360-288)/(5-4)=(72)/(1) \end{gathered}`

Hence, the constant rate of change is 72.
