 // e) Describe what the expression Number(carPrice.replaceAll(",","")) is doing - what is the purpose of this expression?
-// The expression `carPrice.replaceAll(",", "")` removes all commas from the string `carPrice`, converting it to a number that can be used in mathematical operations. This is necessary because the original value is a string with commas (e.g., "10,000"), which cannot be directly used in arithmetic calculations. The `Number()` function then converts the resulting string (e.g., "10000") into a numeric value.
