In a new page, write a function called cashRegister that takes a shopping cart object. The object contains item names and prices (itemName: itemPrice). The function should return the total price (plus tax) with the $ and the fixed decimal position of 2 places. Example (feel free to make your cart items different)

CONST tax = .06; // Input the cart object containing all the items. var cartForParty = { banana: "1.25", handkerchief: ".99", Tshirt: "25.01", apple: "0.60", nalgene: "10.34", proteinShake: "22.36" }; // Output cashRegister(cartForParty)); // should display "Cart total is $60.55 plus $3.63 tax". 

Use a button to Output the CashRegister results (to an alert box).
