### Bank Interest
JavaScript arithmetic works with numeric values stored in variables. A clear solution reads the needed values, computes the formula with `+`, `-`, `*`, `/` or `**`, and prints only the final result.

Hints
+
['Write the formula using named intermediate values if it contains more than one operation.', 'After each iteration, it should be clear what has already been accumulated and what remains to be processed.']
ANSWER
Solution
+
const fs = require('fs');
const input = fs.readFileSync(0, 'utf8').trimEnd();
let [a, r] = input.trim().split(/\s+/).filter(Boolean).map(Number);
let result = (a + (a * r / 100));
console.log(Number.isInteger(result) ? result.toFixed(1) : result);
