Anyone knows why correct solutions are not awarded with points nor marked as solved? (it is said that submissions take longer, but actually they are not taken)

In python:

def solve(meal_cost, tip_percent, tax_percent):
    """
    Prints the calculated value, rounded to the nearest integer.
    :param meal_cost:
    :param tip_percent:
    :param tax_percent:
    :return: The function returns nothing.
    """
    tip = (meal_cost / 100) * tip_percent
    tax = (tax_percent / 100) * meal_cost
    total_cost = meal_cost + tip + tax
    print(int(round(total_cost)))

In the parameterised function define the formula, below is the code:

function solve(meal_cost, tip_percent, tax_percent) { // Write your code here // Calculate tip and tax let tip = meal_cost * (tip_percent / 100); let tax = meal_cost * (tax_percent / 100);

// Total cost
let totalCost = meal_cost + tip + tax;
    }

// Round to nearest integer and print
console.log(Math.round(totalCost));

}

Using explicit type casting to convert double into an int

double tip = meal_cost/100*tip_percent; double tax = meal_cost/100*tax_percent;

int total_cost =  (int)(meal_cost+tip+tax);
System.out.println(total_cost);

1 liner in java (Split in 2 lines for understanding)

int total = (int) Math.round( meal_cost * (1 + ( (double)tip_percent / 100) + ( (double)tax_percent / 100)));
System.out.println(total);
