Question

The yearly profits of a company are shown in the table.

Which answer describes the average rate of change from Year 2 to Year 4?
A Profits increased by an average of $10,600 per year
from Year 2 to Year 4.
B Profits increased by an average of $21,600 per year
from Year 2 to Year 4.
C Profits decreased by an average of $21,600 per year
from Year 2 to Year 4.
D Profits decreased by an average of $10,600 per year
from Year 2 to Year 4.

Answer 1

Explanation:

Hi, Emily. The average rate of change can be calculated by adding all the profits together and dividing by the different profits (4 profits all together A to D) so 10,600+21,600+-21,600+-10,600= 0

0/4= 0

So we can best describe this as 0 or nothing at all as it hasnt changed from year 2 to 4.
