Monthly Payment

[alex1050]

I'm having trouble calculating the right interest expense. The solution for interest expense is 2294.48 but cant get it.

#include <stdio.h>
#include <stdlib.h>
#include <math.h>

int main ()
{
	double P,R,Y,M,X,A,MP,T,I;
	printf("Enter the Principle:\n");
	scanf("%lf",&P);
	
	printf("Enter the Rate:\n");
	scanf("%lf",&R);
	
	printf("Enter the Years:\n");
	scanf("%lf",&Y);
	
	
	R = R/1200;
	

	M = Y * 12;
	
	X=1+R;
	
	
	
	A=pow(X,M)-1;
	
	MP =( R + R / A) * P;
	T = MP * M;
	I = R * MP;
	
	printf("Monthly Payment is: %.2lf\n",MP);
	printf("Total Payment is: %.2lf\n",T);
	printf("Interest Expense is: %lf\n",I);
	
	
	
	
	
	return 0;
	
    
}
