+Answer
+a) In this section of the code, we have function calls  appear 5 time through out the code. Here is each of them on the line of code that
+they are call:
+  - Number(carPrice.replaceAll(",","")); in line  4 is a function calls because the .replaceALL is being executed
+  - Number(priceAfterOneYear.replaceAll(",", "")); in line 5 is also a function call because .replaceAll is being executed.
+  - Inside the Number() function the .replaceAll in both line 4 and 5 is also a function call because the the parent function is also
+   being executed.
+  - the console.log is a function calls
+So the total amount of function call in this code is 5
+
+b) The main error for the when the running this line of code if for the missing right parameter after the double quote, so fix this 
+just add the coma right after the double quote.
+
+c) There are 2 reassign variable statement at line 4 and line 5.
+
+d)There are 4 total variable declarations in this code:
+ - let carPrice = "10,00"; line 1
+ - let priceAfterOneYear ="8,543"; line 2
+ - const priceDifference = carPrice - priceAfterOneYear; line 7
+ - const percentageChange = (priceDifference / carPrice) * 100; line 8
+
+e) The expression Number(carPrice.replaceAll(",","")) are doing 2 main purpose, 
+ - The first purpose is to remove the coma from the string number "10000" and "8543".
+ - Is the changing the string number to number data type.
