Solve simple investment problems using the simple interest rate method?

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.


How do you solve interest rate math problems?

First you figure out the Principal, then you find the interest rate and then find the Time someone gave you to pay back loaned or borrowed money.Formula: Simple Interest= Principal*Rate*TimeExample: Principal-$25,000 Interest Rate- 6.25 simple interest- 6 years$25,000 x .0625 x 6= $9375!
