If we know that 30% of the time is used after 9 minutes we can write this mathematically as:

$0.30x = 9$
By solving for x we can determine the total time allowed to play games and so:

$x = \frac{9}{0.30} = 30$
The total time allowed to play games is 30 minutes. Since 9 minutes have lapsed 30-9=21 minutes left to play.

The problem has the equation:

f(x) = (3) ^ (x/2)

In order to get the average increase in the number of flowers being pollinated from day 4 to day 10, then we need to use the equation substituting x with 4 to 10

f(4) = 9
f(5) = 12.59
f(6) = 27
f(7) = 46.77
f(8) = 81
f(9) = 140.30
f(10) = 243

Then add all the values and divide it by 7
= 559.66 / 7
= 79.95

So the correct answer is 79.95
