Calculate annually compounded interest

Mathematics
1 answer:
Hunter-Best [27]2 years ago
3 0

Answer:

$2,851.80

Step-by-step explanation:

Lets use the compound interest formula to solve:

A=P(1+\frac{r}{n} )^{nt}

<em>P = initial balance</em>

<em>r = interest rate (decimal)</em>

<em>n = number of times compounded annually</em>

<em>t = time</em>

First, change 1.1% into a decimal:

1.1% -> \frac{1.1}{100} -> 0.011

Next, plug the values into the equation:

A=2,700(1+\frac{0.011}{1})^{1(5)}

A=2,851.80

She will have $2,851.80 after 5 years.

World population is approximately upper p equals 6.4 left-parenthesis 1.0126 right-parenthesis superscript t, with upper p in bi
Leviafan [203]

Given equation is

P=6.4(1.0126)^t

It gives approx world population in billions for t years since 2004.


Answer(a):

Compare with growth formula P=a(b)^t, we get:

growth factor b = 1.0126

We know that if r is the percent rate of growth then

1+r=b

1+r=1.0126

r=0.0126

Hence the yearly percent rate of growth of the world population is 0.0126 or 1.26%.


Answer(b):

To find worlds population in 2004, plug t=0 because year is counted from 2004.

P=6.4(1.0126)^0 = 6.4*1 = 6.40

Hence answer is 6.40 billion.


To find worlds population in 2018, plug t=2018-2004=14 because year is counted from 2004.

P=6.4(1.0126)^{14} = 6.4*1.19160117479 = 7.62624751867

Hence answer is approx 7.63 billion.


Answer(c):

Average rate of change of the world population between 2004 and 2018 is given by:

\frac{P\left(Year_{2018}\right)-P\left(year_{2004}\right)}{2018-2004}

=\frac{P\left(14\right)-P\left(0\right)}{14-0}

=\frac{7.63-6.40}{14}

=0.0878571428571

Hence answer is approx 0.0878571428571 billion per year.

To convert it into millions, multiply by 1000

So we get 0.0878571428571*1000 = 87.8571428571

Which is approx 88 to the nearest integer

Hence final answer is approx 88 millions per year.
