Второ решение с тернарен оператор:

function cinema(input) {
    let screeningType = input[0]
    let rows = Number(input[1])
    let columns = Number(input[2])

    let ticketPrice =
        screeningType === "Premiere" ? 12.00 :
            screeningType === "Normal" ? 7.50 : 5.00;

    console.log(`${(rows * columns * ticketPrice).toFixed(2)} leva`);
