(1 point) The monthly payment for a home loan is given by a function f(P,r, N) where P is the principal (the initial size of the loan), r the interest rate, and N the length of the loan in months. Interest rates are expressed as a decimal: A % interest rate is denoted by r= 0.09. If P = 350000, 0.09, and N = 240(a 20-year loan), then the monthly payment is f(350000, 0.09, 240) = 1241. Furthermore, with these values we have af ap = 0.0054, af dr = 8948, af ƏN = -1.3151 Estimate: (a) The change in monthly payment per 3000 increase in loan principal: Af ≈ dollars (b) The change in monthly payment if the interest rate changes from r = 0.09 to r = 0.105: Af dollars (c) The change in monthly payment if the length of the loan changes from 20 to 23 years: Af dollars
