Eric has $100,000 in savings account.The interest rate is 8 % per year and is not compounded.To the nearest Dollar,how much will

Roman55 [17]

Answer:

To calculate the simple interest, we say

S.I = (PxRxT)/100

Where P = the principal amount

R= rate in terms of %

And T= time.

Now P= $100 000

R= 8%

T= 3 years

S.I= (100,000 x8 x3)/100

=$2 400 000/100

= $24, 000

So the interest is 24000

Total amount he will be having = 100000 + 24 000

The total money he will be having in 3 years time = $124 000

the birth rate in a certain country in 1994 was 14,6 birthd per thousand population. in 2004 the birth rate was 14.32 per thousa

amm1812

Answer:

$y(x)=-0.028x+14.6$

Step-by-step explanation:

Birth Rate in 1994 = 14.6 births per thousand population.

Birth Rate in 2004 = 14.32 births per thousand population.

A linear equation is of the form: y=mx+c

Where:

x=years after 1994
y=the birth rate
m=Yearly Birth Rate

First, we determine the birth rate per year

$m=\dfrac{14.32-14.6}{10-0}\\=\dfrac{-0.28}{10}\\m=-0.028$

Therefore, a linear equation that relates y in terms of x is of the form:

$y(x)=-0.028x+c$

When x=0, y=14.6

14.6=-0.028(0)+c

c=14.6

Therefore, the linear equation that relates y in terms of x is:

$y(x)=-0.028x+14.6$
