Bat + ball = 1.10
Bat = ball + 1
---
(ball + 1) + ball = 1.10
2ball + 1 - 1 = 1.10 - 1
2ball = .10
2ball / 2 = .10 / 2
ball = .05

I get why it could be .05¢, but why not .10¢??

There's two criteria that has to be met. Total amount of $1.10 and the bat costing $1 more than the ball. If the ball costs 10¢, then the bat, at 1$, is 90¢ more.
100-10=90.
At 5¢ for the ball, the math checks out.
105-5=100. 105+5=110.

They say 50% of students at Harvard got this question wrong too, so don't feel so bad.

I immediately thought 10¢ too until I figured it couldn't be that easy.

If its 0.10, it still satisfies the bat costing a dollar more, no?

No. The total would then be 1.20.

If the ball costs 10¢ and the bat $1, the bat is only 90¢ more than the ball.

Other.
.10¢ is only 1/10 of a penny.

Better one:

12+3=915
4+2=22
54+45=999

____+_____=123?
