Question

Interest on a credit card's unpaid balance is calculated using the average daily balance. Suppose that netBalance is the balance shown in the bill, payment is the payment made, d1 is the number of days in the billing cycle, and 2 is the number of days payment is made before billing cycle. Then, the average daily balance isc

average Daily Balance (net Balance" di-payment d2)/d1

If the interest rate per month is, say, 0.0152, then the interest on the unpaid balance is

interest average DailyBalance 0.0152

Write a program that accepts as input netBalance, payment, d1, 2, and interest rate per month. The program outputs the interest. Format your output to two decimal places.

Answer 1

#include <stdio.h>






int main()
{
    float netBalance,d1,payment,interest,d2,monthlyInterestRate,averageDailyBalance;


    printf("Enter net Balance: \n");
   scanf("%f",&netBalance);
   
    printf("Enter payment made: \n");
    scanf("%f",&payment);
    printf("Enter number of days in the billing cycle: \n");
    scanf("%f",&d1);
    printf("Enter number of days payment is made before billing cycle: \n");
    scanf("%f",&d2);
   printf("Enter interest per month: \n");
 	scanf("%f",&monthlyInterestRate);




    averageDailyBalance = (netBalance * d1 - payment * d2)/d1;
    interest = averageDailyBalance * monthlyInterestRate;
	printf("Interest is %0.2f",interest);
   
    return 0;
}
