If samantha can pay off her loan in 36 months at a 10% interest rate rather than in 48 months at a 12% interest rate, how much money will she save in interest charges on her $6,000 loan?

I=6,000×0.10×(36÷12)
I=1,800

I=6,000×0.12×(48÷12)
I=2,880

She saved
2,880−1,800=1,080

The answer is c because you turn 17.5% into a decimal which gives you .175 then you times that by $361.35 which gives you 63.23625 but then you round that which gives you 63.24. then you at 63.24 pulse 361.35 and you round it which gives you $425
