### Ticket Booking System

`if / else if / else` chooses a branch from boolean conditions. Comparisons such as `<`, `>=`, `===` and logical operators `&&`, `||`, `!` combine the exact rules that decide which output is valid.

['Translate every case from the statement into a boolean condition before writing branches.', 'Do not mix the loop counter with the accumulated answer; those variables serve different roles.']

const fs = require('fs');
const input = fs.readFileSync(0, 'utf8').trimEnd();
let [f, n, b, p] = input.trim().split(/\s+/).filter(Boolean).map(Number);
let cost = n * p;
if ((n <= f) && (cost <= b)) {
    console.log("BOOKED", (b - cost));
} else {
    console.log("REJECTED");
}
