06. Repainting

function repainting(input){

    let nylon = Number(input[0]);
    let paint = Number(input[1]);
    let thinner = Number(input[2]);
    let hours = Number(input[3]);

    let materialsPrice = (nylon + 2) * 1.50 + paint * 14.50 * 1.1 + thinner * 5 + 0.40;
    let workersPrice = materialsPrice * 0.30 * hours;

    console.log(materialsPrice + workersPrice);
}


Тарикатско решение :)

function repainting(input){

    let materialsPrice = (Number(input[0]) + 2) * 1.50 + Number(input[1]) * 14.50 * 1.1 + Number(input[2]) * 5 + 0.40;
    let workersPrice = materialsPrice * 0.30 * Number(input[3]);

    console.log(materialsPrice + workersPrice);
}
