Answer:
75%
Step-by-step explanation:
First, take a look at the equation.
4, 500(1.75)^t
4500 is the y-intercept, or the INITIAL VALUE, as given in the information.
Exponential Growth is shown when the percentage is added to 1. For example, in this case, it's 1+0.75, which equals 1.75.
Therefore, annually, it increases by 75%.
