Hello I am having problems with this question, may you help me find the steps needed to solve this?

Laura Kennedy needs to borrow 54993 to pay for NBA season tickets for her family. She can borrow the amountfrom a nance company (at 5.1% add-on interest for3 years) or from the credit union (36 monthlyr payments of$168.92 each}. Laura takes the credit union loan. At the time of her thirtieth payment she pays it off. If the credit union uses the rule of 78 for computing unearned interest, how much will she save by paying o the loan with the thirtieth payment? The amount that she will save by paying in full now is 5 (Round tn the nearest cent as needed.)
