Richard was able to payoff the loan at the end of 30 months. Using the Actuarial method find he unearned interest, and payoff amount.

614*48=29472
29472-24905=4567
4567/24905*100=18.34
The APR will be 9%

3. not that simple

let the monthly rate be i
614 (1 - (1+i)^-48)/i = 24905
very tough to solve
I will let Wolfram do it

https://www.wolframalpha.com/input/?i=sove+614+(1+-+(1%2Bx)%5E-48)%2Fx+%3D+24905

i= .00709283
12i = .08511... or 8.511% per annum compounded monthly
