make transition table and draw the dfa diagram

Design a DFA that describes the behavior of a vending machine which accepts Rupees and coins, and charges PKR 50.50 per soda. Once the machine receives at least PKR 50.50, it will allow the user to select a soda. Self-loops represent ignored input: the machine will not dispense a soda until at least PKR 50.50 has been deposited, and it will not accept more money once it has already received greater than or equal to PKR 50.50
