how can i write my answer for part two so that it matches the question

Recall the following situation: A $120,000 home mortgage for 30 years at 7% has a monthly payment of $839.06. Part of the monthly payment is paid toward the interest charge on the unpaid balance, and the remainder of the payment is used to reduce the principal. The amount that is paid toward the interest is: u = M-(M-1)(1 + " The amount that is paid toward the reduction of the principal is: In these formulas, Pis the size of the mortgage, ris the interest rate, Mis the monthly payment, and is the time in years. PARTE: (1) Use wolframalpha.com to graph each function in the same coordinate plane. Remember that we are graphing in a two dimensional space, so you will need to refer to both equations as "ywhen setting up the plot statement in this program. You might also want to let x represent time. Make sure you show all thirty years of mortgage payments You must print your graph to turn in as part of the project. (2) Based on your graph, approximate the year when the monthly payment is evenly divided between interest and principal reduction Discuss the distribution of the payment before and after this time. Use at least three complete sentences. (3) If the repayment period was changed from thirty years to twenty years, the monthly payment would be 5966.71. Repeat parts (1) and (2) using this new repayment period. (4) Compare the results obtained for a thirty year repayment period versus a twenty year repayment period. Be sure to address similarities and differences. A minimum of four sentences is required. PARTI: We can get an estimate of the time when the monthly payment is divided evenly between interest and principal reduction from the graph. To get a closer result we can solve by using techniques involving exponential equations. For this part of the project you need to set u and v equal and solve for the variablet. Use the values given in the situation for this mortgage loan. All work should be shown, and if necessary, round your results to three decimal places. You should do this for both the 30 year mortgage and the 20 year mortgage
