Answer 1

The costant rate of change can be expressed as,

`R=(\Delta C)/(\Delta h)`

Consider table H.

The constant rate of change can be calculated as,

`\begin{gathered} R=(\Delta C)/(\Delta h)=(9.75-3.25)/(3-1)=3.25 \\ R=(\Delta C)/(\Delta h)=(16.25-9.75)/(5-3)=3.25 \\ R=(\Delta C)/(\Delta h)=(22.75-16.25)/(7-5)=3.25 \end{gathered}`

Therefore, table H shows a constant rate of change of $3.25.
