+# --description--
+
+There are four types of common coins in [US](https://en.wikipedia.org/wiki/United_States) currency:
+
+<ul>
+  <li>quarters (25 cents)</li>
+  <li>dimes (10 cents)</li>
+  <li>nickels (5 cents), and</li>
+  <li>pennies (1 cent)</li>
+</ul>
+
+<p>There are six ways to make change for 15 cents:</p>
+
+<ul>
+  <li>A dime and a nickel</li>
+  <li>A dime and 5 pennies</li>
+  <li>3 nickels</li>
+  <li>2 nickels and 5 pennies</li>
+  <li>A nickel and 10 pennies</li>
+  <li>15 pennies</li>
+</ul>
+
+# --instructions--
+
+Implement a function to determine how many ways there are to make change for a dollar using these common coins (1 dollar = 100 cents)
+
+# --hints--
+
+`countCoins` should be a function.
+
+```js
+assert(typeof countCoins === 'function');
+```
+
+`countCoins()` should return 242.
+
+```js
+assert.equal(countCoins(), 242);
+```
+
+# --seed--
+
+## --seed-contents--
+
+```js
+function countCoins() {
+
+  return true;
+}
+```
+
+# --solutions--
+
+```js
+function countCoins() {
+  let t = 100;
+  const operands = [1, 5, 10, 25];
+  const targetsLength = t + 1;
+  const operandsLength = operands.length;
+  t = [1];
+
+  for (let a = 0; a < operandsLength; a++) {
+    for (let b = 1; b < targetsLength; b++) {
+      // initialise undefined target
+      t[b] = t[b] ? t[b] : 0;
+
+      // accumulate target + operand ways
+      t[b] += (b < operands[a]) ? 0 : t[b - operands[a]];
+    }
+  }
+
+  return t[targetsLength - 1];
+}
+```
