Where is the question?
OpenStudy (anonymous):
what will the amount be after 4 years
OpenStudy (anonymous):
You can use the formula for a simple interest rate which is
interest = principal * rate * time
You will need to know the interest rate though.
OpenStudy (anonymous):
the interest rate is 6%
OpenStudy (anonymous):
I = 1,000 * 0.06 * 4 = 240
so there will be $1,240 after 4 years.

what about after 17 years?
OpenStudy (anonymous):
Just substitute 17 in for 4.
OpenStudy (anonymous):
i dont get it? :(
OpenStudy (anonymous):
You have the initial amount which is called the principal. You then multiply that by the amount of interest earned, 6%, converted into decimal form which is 0.06. Then multiply that by the amount of time.
OpenStudy (anonymous):
For 17 years it would be
I = 1000 * 0.06 * 17 = 1020
Add that to the principal and you have your total after 17 years.
1020+ 1000 = 2020

Solve this equation:
1000 * 0.06 * x = 1,500
OpenStudy (anonymous):
