Let's pretend Ты saw a t-shirt worth 97 cents at a store. Since Ты don't have any cash along with you, Ты borrowed 50 cents from your mom and 50 cents from your dad as well. So now Ты have $1. Ты bought the рубашка and received a change of 3 cents. Ты returned 1c to your mom, 1c to your dad and Ты kept the remaining 1c.

So now Ты owe them 49c each.Here's the question:

49c + 49c = 98c is the total of how much Ты owe them, plus the 1 cent that Ты kept = 99c.

It was supposed to be $1. Where's the missing penny?
