Determine the present value P you must invest to have the future value A at simple intrest rate r after time t. A=$14,000, r=9.5
Ivan

Answer:

$10,144.93

Step-by-step explanation:

Amount formula; A = (Principal* rate* time) +Principal

A= (P*r*t) +P

A= 14,000

r= 9.5% OR 0.095 as a decimal

t= 4

Plug the numbers into the formula;

14,000 = (P* 0.095 *4 ) +P

14,000 = 0.38P +P

14,000 = 1.38P

Divide both sides by 1.38 to solve for P;

14,000/1.38 = P

P= 10,144.9275

Therefore, the present value (Principal) = $10,144.93

A number when divided by 780 gives remainder 38 .What
baherus [9]

Given:

A number when divided by 780 gives remainder 38.

To find:

The reminder that would be obtained by dividing same number by 26.

Solution:

According to Euclis' division algorithm,

a=bq+r                ...(i)

Where, q is quotient and 0\leq r is the remainder.

It is given that a number when divided by 780 gives remainder 38.

Substituting b=780,\ r=38 in (i), we get

a=(780)q+38

So, given number is in the form of 780q+38, where q is an integer.

On dividing 780q+38 by 26, we get

\dfrac{780q+38}{26}=\dfrac{780q}{26}+\dfrac{38}{26}

\dfrac{780q+38}{26}=30q+\dfrac{26+12}{26}

\dfrac{780q+38}{26}=30q+\dfrac{26}{26}+\dfrac{12}{26}

\dfrac{780q+38}{26}=30q+1+\dfrac{12}{26}

Since q is an integer, therefore (30q+1) is also an integer but \dfrac{12}{26} is not an integer. Here 26 is divisor and 12 is remainder.

Therefore, the required remainder is 12.
