We can model this scenario by using the exponential growth formula and plugging in values we know:
A, the resulting amount, is unknown
P, the principle (starting) amount, is 5120
r, the rate at which P increases, is .05 (if a .2 increase spans over 4 years, there is a .05 increase each year)
t, the amount of time that has passed, is 4
The equation now looks like this:
To find A, we just need to simplify the other side:
In 2013, there were ~6224 Miami highway accidents (I rounded up because the amount was more than 6223, and you can't have a fraction of a car accident).
