3 guys go into a hotel. The manager charges 30$ for the room. They take the key and go to their room. The manager realizes he billed them the wrong price, so he asks an employee to return them 5$. On the way, the employee cannot figure how to split up 5$ evenly in 3, so he keeps 2$ and gives the guys back 1$ each.
Accounting says is balances. Math says it does not.
Accounting: 30$ - 2$ - 3$ = 25$. No money lost.
Math: Each guy receives 1$ back. So each paid 10 - 1 = 9$. The employee kept 2$. 3 guys * 9 $ = 27 $. Add the 2$ and you end up with 29$. NOW WHERE DID THE MISSING 1$ GO ???
first of all, you are subtracting the dollar away from the guys. Then you are adding it in from the employee. It’s a problem of right math, wrong place.
If you take away the $2 the worker kept from the $27 the guys paid, you have $25. Since you are adding it in, you are going to miss a dollar. It’s math in the wrong direction.
You don’t add the $2 tip. When each guy payed their $10, the tip was included. Thus, by adding $2 to the $27, you’re essentially couting the tip twice.
The room cost $25, the tip was $2 (for a total of $27), and then each man received $1 = $30.
