Answer 1

class Travelling {
    calculateExpenses (date, number) {
        if(number <= 0) {
            console.log('Incorrect number of km.')
            return;
        }


        let total = 0;
        for(let i = 1; i <= number; i++) {
            total += i < 100 ? 1.20 : 1.50;
        }


        console.log('The date: ' + date);
        console.log('The number of kilometres travelled: ' + number);
        console.log('The total expenses due : R' + total);
    }
}
