Question

I’m fairly sure it’s increasing, I just can’t tell by how much

Answer 1

The rate of change is given as

`\text{rate}=(48400-46680)/(550-530)`

which gives

`\begin{gathered} \text{rate}=(1720)/(20) \\ \text{rate}=86 \end{gathered}`

Since the result is positive, the answer is the costs are increasing at a rate of $86 per item
