 // e) Describe what the expression Number(carPrice.replaceAll(",","")) is doing - what is the purpose of this expression?
+// The expression `Number(carPrice.replaceAll(",", ""))` is converting the string representation of the car price, which includes commas (e.g., "10,000"), into a number. The `replaceAll(",", "")` part removes all commas from the string, resulting in "10000", and then the `Number()` function converts this string into a numeric value (10000). This is necessary for performing arithmetic operations on the price.
