A combo meal is a great way to enjoy a variety of flavors in one convenient package. It typically includes a main dish, like a burger or sandwich, paired with sides such as fries and a drink. The combination offers value for money while satisfying different cravings. For example, the Burger Urge menu features a wide range of burger options that can easily be turned into combo meals, offering both delicious and filling choices for all types of tastes. Whether you're in the mood for something classic or a bit more adventurous, a combo meal is a satisfying option.

To calculate the fixed profit in each scenario, you compare the combined price of a burger and soda with the price of the combo meal. The difference between the combo price and the individual items, divided by two, gives the fixed profit. This method can be applied to any fast-food menu, such as the one at rocomamasmenu, to determine the profit margin on their items.

Great discussion. I hope this would help me with https://cavamenuprice.com/cava-houston-heights-menu/

c#

public static int profit(int b, int s, int c)

{
// Return the fixed profit.
    int markup = (b+s-c);
    return markup;
    Console.WriteLine(markup);
}

Javascript -- rewrote main() function instead

function main() {
    const ws = fs.createWriteStream(process.env.OUTPUT_PATH);
    ws.write(Array(+readLine()).fill().map(_ => readLine().split(' ').map(x => +x)).map(x => x[1] - x[2] + x[0]).join('\n'));
    ws.end();
}
