Answer:
$ 845
Step-by-step explanation:
James' joining salary is $66,640
In 8 years his salary will increase to $73,400.
Now, that is an increase of $73,400-$66,640=$6760 in a total of 8 years.
This means that if in 8 years the salary increases by $6760, then in 1 year or in per year basis, the increase on James salary (also called the rate of change) will be:
[tex]\frac{73400-66640}{8} =845[/tex]
In the above we have used the slope formula as:
[tex]\frac{y_2-y_1}{x_2-x_1}[/tex] where, [tex](x_2,y_2) are (8,73400)[/tex] and (x_1,y_1)=(0, 66640).
