<u><em>3,525 Students total after 7 years.</em></u>

Step-by-step explanation:

First I did 2.5% of 3,000 and got 75. I then did 75 * 7= 525. So the school gained 525 students in 7 years so Then To get the totl amount of students in the school after 7 years I did 3,000 + 525 and got a final result of 3,525.

This explanation and my work is 100% correct , yet the answer is not listed, You can do what you want with my answer, but I tried to help. If I had to make an educated guess about what the actual answer is then I would say the answer is A. But like I said before I'm not 100% SURE that A is correct.

An investment earn 6% simple interest. What amount of principal is need to have $3000 after 5 years

irakobra [83]

Answer:

The amount of $1000 principal is needed to have $3000 after 5 years.

Step-by-step explanation:

As the interest formula is

$I=Prt$

Where

P is the principle

r is the rate in decimal

t is the time in years

Substituting the following values in the interest formula and solve for P

I=$3000

r = 6% = 6/100 = $0.06$

t = 5

so the equation becomes

$I=Prt$

$3000=P\left(0.06\right)\left(5\right)$

switch both sides

$P\left(0.06\right)\left(5\right)=3000$

$P\left(0.3\right)=3000$

$P=10000$ $

Therefore, the amount of $1000 principal is needed to have $3000 after 5 years.
