I saw a shirt for $97. I borrowed $50 from mom and $50 from dad. After purchasing I return $1 to mom and $1 to dad and kept $1 for me. I now owe $49+$49=$98 plus $1 I kept my self which is $99, Where did $1 go?

You still ow $49 to each, bruh. since you started with $100 and returned $2 and kept $1 thats all you had after purchasing

Step-by-step explanation:

you borrowed $50 from both so you have $100

after buying a $97 shirt, you have $3

but gave $1 back to each. so you have $1 which you kept.

so you borrowed $98

* since you gave the $1 back after purchasing. you had enough.
