Please see below to help me with the explanation with working out the solution.

To help open up a wine bar, Jenny borrowed money from an online lending company. She took out a personal, amortized loan for $42,000, at an interest rate of 6.85%, with monthly payments for a term of 7 years. For each part, do not round any intermediate computations and round your final answers to the nearest cent. If necessary, refer to the list of financial formulas. (a) Find Jenny's monthly payment. X ? (b) If Jenny pays the monthly payment each month for the full term, find her total amount to repay the loan. (c) If Jenny pays the monthly payment each month for the full term, find the total amount of interest she will pay. $
