The average rate of change of the area from the original photograph to the fourth enlargement, to the nearest tenth is 5.4.

Average rate of change

First step

0-1=18.8-15

0-1=3.8

1-2=23.4-18.8

1-2=4.6

2-3=29.3-23.4

2-3=5.9

3-4=36.6-29.3

3-4=7.3

Second step is to find Average rate of change:

Average value=(3.8+ 4.6 +5.9 +7.3)/4

Average value=21.6/4

Average value=5.4

Therefore the Average rate of change is 5.4
