// Variable which can change to hold number of pizza orders
let orderCount = 0;

// Function for placing pizza orders including toppings & crust type
const takeOrder = (topping, crustType) => {
// Increment the order numbers by one each time function is called  
  orderCount++;
// Print the type of pizza ordered after the function is called  
  console.log(`Orders: ${crustType} pizza topped with ${topping}`);
}

// Function for calculating each orderCount by $7.50
const getSubTotal = () => {
  return orderCount * 7.5;
}

// Calling function getSubTotal within function getTax to calculate sales tax of 6% to sub total of pizzas
const getTax = () => {
  return getSubTotal() * 0.06;
}

const getTotal = () => {
  return getTax() + getSubTotal();
}

// Calling function takeOrder and passing arguments for toppings & crust type
takeOrder('pepperoni', 'thin crust');
takeOrder('pepperoni', 'thin crust');
takeOrder('pepperoni', 'thin crust');

// Calling function getSubTotal with orderCount argument to print sub total of orders
console.log(getSubTotal());

// Calling function getTax to print the sales tax of getSubTotal
console.log(getTax());

// Calling function getTotal to print getSubTotal * getTax for total price
