Answer:
The average rate of change per year is 3,000,000.
Explanation:
If you look at the year spam you will see that the period in question starts in 1992 and finishes in 1998, which is <em>six</em> <em>years</em>.
The total profit growth during these 6 years would then be 21,000,000 take off 3,000,000<em> </em>resulting in <em>18,000,000</em>.
In order to get the average rate of change per year, you should divide the total amount of profit growth, 18,000,000 by the six years it took for it to grow. Therefore the answer would be:
18,000,000 ÷ 6 = 3,000,000
