We can model the function between a and b as a linear function of negative slope because it is a short interval and the change is not very significant.
We have then that the average rate of change in that interval is:
m = (f (a) - f (b)) / (a-b)
Substituting the values:
m = (34.25 - 26) / (2.5-3.6)
m = -7.5
Negative, because the function decreases in that interval.
Answer:
a reasonable estimate of the average rate of change of the height of the rocket, in meters per second, between a and b seconds is:
m = -7.5 m / s

Step-by-step explanation:
Price of cupcake per dozen = $15
Projected amount of sales > $120
In other to make such amount in sale, we need to obtain the number of dozens of cupcake :
Project amount of sales / price per dozen
> $120 / $15
> 8 dozens
