            price = km * 0.79 + 0.7;
        } else {
            price = km * 0.9 + 0.7;
        }
    }  else if (km >= 100) {
        price = km * 0.06;

РЕШЕНИЕ С ТЕРНАРЕН ОПЕРАТОР:

function transportPrice(input) {
    let km = Number(input[0]);
    let time = input[1];

    let price = km < 20 ? km * (time == "day" ? 0.79 : 0.9) + 0.7 : km >= 100 ? km * 0.06 : km * 0.09;

    console.log(`${price.toFixed(2)}`);
}

Или леко тарикатската:

function transportPrice(input) {
    let km = Number(input[0]);

    console.log(`${(km < 20 ? km * (input[1] == "day" ? 0.79 : 0.9) + 0.7 : km >= 100 ? km * 0.06 : km * 0.09).toFixed(2)}`);
}
