After finishing her management degree, Jenny started a job with a fixed percentage for an annual raise. Jenny’s annual salary is

nadya68 [22]

Answer:

After five years, Jenny has an annual salary of $137,008.67

the difference of Donald’s and Jenny’s salaries is $17,791.77

Step-by-step explanation:

Jenny's annual salary = $A = 100000(1.065)^t$

Donald's annual salary = $A=85000(1.07)^t$

We need to find out annual salary for Jenny after 5 years

Here 't' represents the number of years

So we plug in 5 for t and find out A

Jenny's annual salary = $A = 100000(1.065)^t$

$A = 100000(1.065)^5=137008.6663415625= 137008.67$

After five years, Jenny has an annual salary of $137,008.67

Now we find annual salary for Donald after 5 years

So we plug in 5 for t and find out A

Donald annual salary = $A = 85000(1.07)^t$

$A = 85000(1.07)^5=119216.8971095= 119216.90$

To find the difference of Donald and Jenny salary we subtract

Jenny's salary - Donald's salary after 5 years

137,008.67 - 119,216.90= 17791.77

the difference of Donald’s and Jenny’s salaries is $17,791.77

A country's population in 1992 was 72 million. In 1998 it was 76 million. Estimate the population in 2012 using the exponential

stepan [7]

We assume the annual percentage increase is the same. We will work out the constant k using the formula

We have
P = 76
A = 72
t = 6 years (from 1992 to 1998)

Substitute into the formula
$76=72e^{6k}$
$\frac{76}{72}=e^{8k}$
Take log both sides give
$ln( \frac{76}{72})=ln(e^{6k})$
$0.05406722127=6k$
$k=0.009$

We can now work out the number of population by the end of 2012 using the formula

We have
A = 72 million
k = 0.009
t = 10 years (1992 to 2012)

$P=72e^{0.009*10}$ $P=78.78$ ≈79 million
