Algebra.Com's Answer #690589 by jorel1380(3719)![]() ![]() You can put this solution on YOUR website! A)The following formula is used to calculate the fixed monthly payment (P) required to fully amortize a loan of L dollars over a term of n months at a monthly interest rate of c. [If the quoted rate is 6%, for example, c is .06/12 or .005]. \n" ); document.write( "P = L[c(1 + c)^n]/[((1 + c)^n)) - 1]. \n" ); document.write( "So, we have: \n" ); document.write( "P=216000((.00375*(1+.00375)^360))/((1+.00375)^360)-1))) \n" ); document.write( "P=216000(0.01442886768736313153815180601079/(2.847698049963501743507148269543) \n" ); document.write( "P=216000(0.00506685309825880826287390636924)=$1094.44 as the required monthly payment. \n" ); document.write( "B)Using the same formula as last time, we have: \n" ); document.write( "P=216000((.00375*(1+.00375)^240))/((1+.00375)^360)-1) \n" ); document.write( "P=216000 (0.00632649376219962420615722743331) \n" ); document.write( "P=$1366.52 as the monthly payment. \n" ); document.write( "C)Savings in interest would be: \n" ); document.write( "(1094.44*360)-(1366.53*240)=$66032.96 in savings. ☺☺☺☺ \n" ); document.write( " |
