 // You will need to declare a function called toPounds with an appropriately named parameter.
 
 // You should call this function a number of times to check it works for different inputs
+
+
+// REUSABLE FUNCTION SOLUTION:
+
+function toPounds(penceString) {
+    // Remove the trailing 'p' character
+    const penceStringWithoutTrailingPound = penceString.substring(
+        0,
+        penceString.length - 1
+    );
+
+    // Pad with leading zeros to ensure at least 3 characters
+    const paddedPenceNumberString = penceStringWithoutTrailingPound.padStart(3, "0");
+
+    // Extract pounds (all except last 2 digits)
+    const pounds = paddedPenceNumberString.substring(
+        0,
+        paddedPenceNumberString.length - 2
+    );
+
+    // Extract pence (last 2 digits) and ensure it's 2 digits
+    const pence = paddedPenceNumberString
+        .substring(paddedPenceNumberString.length - 2)
+        .padEnd(2, "0");
+
+    // Return the formatted string
+    return `£${pounds}.${pence}`;
+}
+
+// TEST THE FUNCTION:
+
+console.log(toPounds("399p"));    // £3.99
+console.log(toPounds("99p"));     // £0.99
+console.log(toPounds("5p"));      // £0.05
+console.log(toPounds("1000p"));   // £10.00
+console.log(toPounds("12345p"));  // £123.45
