Question

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

Answer 1

Given that:

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

So the rate of change on your earnings last year.:

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

Hence the rate of change on your earnings last year is $3100
