Question

this year you earned $75,500. Last year you earned $72,400. What was the rate of change since last year

Answer 1

This year you earned $75,500. Last year you earned $72,400.

the rate of change:

`\begin{gathered} R=\frac{75500-72400}{1\text{ year}} \\ R=(3100)/(1) \\ R=3100 \end{gathered}`

So the rate of change is $3100 per year
