Brenda can buy a used motorcycle for $1500 cash, or she can pay a down payment of 10% and make 24 monthly payments of $64.80. What is her finance charge if she chooses the second option?

Answer 1

The amount of the down payment is $1500 x 10/100 = $<<1500*10/100=150>>150.
So, the amount Brenda will finance is $1500 - $150 = $<<1500-150=1350>>1350.
Hence, the total cost of the motorcycle if Brenda chooses the second option is $1350 + (24 x $64.80) = $<<1350+(24*64.8)=3007.20>>3007.20.
Therefore, Brenda will pay a finance charge of $3007.20 - $1500 = $<<3007.20-1500=1507.20>>1507.20. Answer: \boxed{1507.20}.
