A bat and a ball costs $1.10 in total.

Question

I’m sure you have heard of this math problem. No matter how many times someone explained this to me I still feel confused. Can someone explain in the simplest way possible?

Answer 1

The problem states two things:

1. “A bat and a ball cost $1.10 in total”

2. “The bat costs $1.00 more than the ball.”

So in other words:

1. Bat+Ball=1.10

2. Bat=Ball+1.00

So if we replaced “Bat” with “Ball+1.00” we get (Ball+1.00)+Ball=1.10, or simply Ball+Ball = 0.10, which means a ball costs 0.05 and so a bat costs 1.05.
