Question

C programming help!

Write a program that reads the electricity consumption (in kWh) and computes the electricity bill based on the following information:

• The first 50 kWh costs 8.5 cents/kWh

• Next 100 kWh costs 9.5 cents/kWh

• Next 100 kWh costs 9.8 cents/kWh

• The consumption above 250 kWh costs 10.25 cents/kWh

Additional surcharge 20% is added to the bill. The input of the program is one integer and the output will be “The total bill is $?.”, where ? is the price of electricity rounded to two decimal places.

Example of input: 303

Corresponding output: The total bill is $34.78.

Answer 1

CODE IN C:

#include <stdio.h>

int main()
{
int n ;
printf("Enter the electricity consumption(in Kwh) : ");
scanf("%d",&n);
float bill = 0 ;
if(n > 250){
bill += (n-250) * 10.25 ;
n = 250 ;
}
if(n > 150){
bill += (n-150) * 9.8 ;
n = 150 ;
}
if(n > 50){
bill += (n-50) * 9.5 ;
n = 50 ;
}
bill += n * 8.5 ;
bill = bill + bill * 0.2 ;
bill = bill / 100 ;
printf("The total bill is $%.2f",bill);

return 0;
}

OUTPUT:
