Welcome to kaju bakery,
Kaju bakery deals with large number of orders of cake. So to handle the cake demand we need a function that takes in the number of servings of cake required and price of cake in dollar and returns the total price for that cake.
We also impose tax of 1$ so keep that in mind too
Have the function named deliver and return the total price customer has to pay in the counter.
also check if the number of servings <= 0 then just return zero.
