Alright, listen up, honey. To solve simple investment problems using simple interest, you just need to multiply the principal amount by the interest rate and the time period. Add the interest to the principal, and voila, you've got your total amount. It's basic math, darling, nothing to lose sleep over.
When each interest calculation uses the initial amount, this is called Simple Interest. The other type is Compound Interest, which uses the current balance as the basis for interest calculation.
Simple interest: 100/6 ie 16.67%
A simple formula can be used to calculate the amount the dollar invested is worth over a monthly period. Use PV*(1+R)/N where PV is your present investment, R is your interest rate and N is the number of investment periods.

it affects the result of your investment excercise by changing the percentage yearly! PS: Your working on your Personal Management Merit badge for trail to Eagle right?
A $5000 investment at an annual simple interest rate of 4.4% earned as much interest after one year as another investment in an account that earned 5.5% annual simple interest. How much was invested at 5.5%?
$2400
the interest rate is lower than on comparable investments
What is the amout of interest that will be earned on an investment of $8000 at 10% simple interest for 3 years
No. I is as described for the stated period.
Compound interest gives you more, but at a low interest rate (less than 10%), the difference is negligible.

To solve problems quickly you must have simple but effective method.
Simple interest (compounded once) Initial amount(1+interest rate) Compound Interest Initial amount(1+interest rate/number of times compounding)^number of times compounding per yr
If the interest is simple interest, then the value at the end of 5 years is 1.3 times the initial investment. If the interest is compounded annually, then the value at the end of 5 years is 1.3382 times the initial investment. If the interest is compounded monthly, then the value at the end of 5 years is 1.3489 times the initial investment.
The amount of interest earned on an investment of C, for y years at r per cent is C*y*r/100.
350*0.025*5 = 43.75
