When me and my parents visited a mall nearby, I saw an item that I really loved to buy which cost 97 pesos but I have no money in my pocket. So I borrowed 50 pesos each on my father and mother in total of 100 pesos. I paid for the item and this vendor gave me 3 pesos for changed. I returned 1 peso on my father and another peso on my mother. So I only owe each of them 49 pesos and the money I have is only 1 peso in me the total is only 99. The question is where is the missing 1 peso to make it a total of 100?​
