Enrollment in a dance studio has grown exponentially since the studio opened. A graph depicting this growth is shown. Determine the percentage rate of growth.

0.25%
1.25%
2.5%
25%

Option (4). 25%

Step-by-step explanation:

The graph attached shows the exponential growth.

Let the graphed function is y =

Here 'r' = Rate of growth

t = Duration of time in years

y = enrollments after time 't' years

Graph shows at time 't' = 0 or initially number of enrollments = 20

After 8 years number of enrollments will be

120 =

6 =

log 6 =

0.77815 =

= 0.0972689

r = 25.1%

r ≈ 25%

Therefore, Option (4) will be the answer.

b.an increase in a causes b to decrease
