A bat and a ball costs $1.10. The bat costs $1 more than the ball. How much does the ball cost?

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 use this math all the damn time in making jewelry.

The ball costs 5 cents.

$0.05

5¢

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.

I feel dumb.

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.

The ball costs 5¢ duh

5 cents.

Ha you got me! Good question

90 cents.

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.

Oh, got it.

5 cents

Other. .10¢ is only 1/10 of a penny.

Yeah, disregard the decimal. It was late when I posted this.

The answer is still "other" lol.

$ .05

Better one: 12+3=915 4+2=22 54+45=999 ____+_____=123?

Saw this online once

12+11?

Pretty sure this was an SAT question lol

5¢ and 1.05$ I believe
