Lavonda took out $65,000 loan with an apr of 15.78%. she plans o pay it back over 10 years. what is her monthly payment ? what is the total amount of the monthly payments? what is the finance charge ?

I think you do the formula I=prt which stands for interest, principal, rate then time.

So you set it up as I= (65,000) (15.78%) (10 years)= $102,570.

I know this answers a part of one of your questions, but I am not sure which one. Sorry. :<

I hope this helps, and I hope you have a good day. c;

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
