Answer to Question #264004 in Algorithms for Bigboss0616

Question

An electric company bases its charges on two rates, customers are charged P25.00 per kilowatt-hour for the first 300 kilowatt-hours used in a month and P30.00 each for all kilowatt-hours used thereafter. Compute for the amount due from a customer after reading the kilowatt-hours used. Assume that there are 100 records of customers.

Answer 1

In C:

#include <stdio.h>
#define RATE1 25.0
#define RATE2 35.0
#define THRESHOLD 300
#define N_CUSTOMERS 100

int main() {
    double amount;
    double charge;
    double total_charge=0.0;


    for (int i=0; i<N_CUSTOMERS; i++) {
        printf("Enter amout consumed by customer %d: ", i+1);
        scanf("%lf", &amount);
        if (amount < THRESHOLD) {
            charge = amount * RATE1;
        }
        else {
            charge = THRESHOLD * RATE1 + (amount - THRESHOLD) * RATE2;
        }
        total_charge += charge;
    }
    printf("Total charge is P%.2f\n", total_charge);


    return 0;
}

In Python

total_charge = 0


for i in range(1, 101):
    amount = float(input(f'Enter amout consumed by customer {i}: '))
    if amount < 300:
        charge = amount * 25
    else:
        charge = 300 * 25 + (amount - 300) * 35
    
    total_charge += charge

print(f'Total charge is P{total_charge:.2f}')
