17.16 is 62.4% of what number?
'is' indicates an equal sign.
62.4% = 0.624
'of' indicates multiplication
'what number' indicates an unknown value that we can call 'x'
17.16 = 0.624 * x
17.16 = 0.624x
Divide 0.624 to both sides:
x = 27.5
Answer:
Decay function, 70% per year.
Step-by-step explanation:
A general exponential function is defined as
...(1)
where, a is initial value, |r| is rate of change and x is time in years.
If r>0, then it is a growth function and if r<0, then it is a decay function.
The given function is

It can be rewritten as

...(2)
On comparing (1) and (2), we get

Since r<0, therefore the given function is a decay function.

Therefore, the given function decreasing by 70% per year.
