no its you not giving them the 1 when you do the math and forget to give 50 cents to each parent when you forgot to add it into the total
you keep that 3 $ till your ready to pay them back..
so we give
mom 48.5
dad 48.5 +
-----------------
=97
now we add that 3$ to the problem
i give mom 1 $ 1+48.5= 49.5
i give dad 1$ 1+48.5= 49.5
so now there left with 99$ and i have 1$ now heres where it gets tricky again, i take that 1 $ and a divide it by 2
so 1 /2 = .50$
so now we take that .50 and add that to moms and we get 50$ to mom and 50$ to dad and problem is solved
