The general formula for exponential growth and decays is:
if k>0 then then it is an exponential growth function. If k<0 then the function represents an exponential decay.
Now we need to classify each of the functions:
1.
The function
can be wrtten as:
comparing with the general formula we notice that k=2, therefore this is an exponential growth.
2.
The function
can be written as:
comparing with the general formula we notice that k=-4, therefore this is an exponential decay.
3.
The function
comparing with the general formula we notice that k=-1, therefore this is an exponential decay.
Answer:
37%
Step-by-step explanation:
If Ramona received an overall pay of $52,561 last year, $23,960 of which was base pay, we can first subtract these two numbers to find the amount she made from her sales commission:
$52,561 - $23,960 = $28,601
In order to find her percent commission, we can set up a proportion:
, where 'p' is her rate of commission
Cross-multiply and divide: 100(28601) = 77300x or 2,860,100 = 77,300x
Or x = 37%
