Hello!</h2>
The answer is: 50% (0.5)
<h2>
Why?</h2>
Exponential growth equations are use to predict the growth (in function of time) using proportional information.
We can calculate the exponential growth using the following formula:

Where,
S, is the starting value
r, is the growth rate
t, is the time
So, we are given the function:

Where,
f(t), is the function,
3, is the starting value (lb)
0.5 (50%) is the growth rate
nt, is the time elapsed.
Hence,
From the given function, we know that the growth rate is equal to 0.5, and it's equal to 50%.
We can turn the growth rate given in real numbers to percent value by multiplying by 100

So, the growth rate is 50%.
Have a nice day!
Answer:
The money which will be owe is $750
Step-by-step explanation:
Given as :
The hospital bill which is charge = $1000
The deductible amount in hospital bill = $250
So, The rest amount will be owned
∴ The Amount which will be owned = Total bill - Deductible bill
Or,The Amount which will be owned = $1000 - $250 = $750
Hence The Amount which will be owned is $750 Answer
