HELPPP The number of members in the Triathlon Club was 36 in 2001 and has increased by 20% each year. Which exponential growth m

levacccp [35]

Answer:

C. y=36(1.2)t

Step-by-step explanation:

The number of members in the Club in t years after 2001 is given by an equation in the following format:

$y = y(0)(1+r)^{t}$

In which y(0) is the number of members in 2001 and r is the growth rate, as a decimal.

The number of members in the Triathlon Club was 36 in 2001 and has increased by 20% each year.

This means that $y(0) = 36, r = 0.2$

$y = y(0)(1+r)^{t}$

$y = 36(1+0.2)^{t}$

$y = 36(1.2)^{t}$

The correct answer is C.
