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.
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.
At 5¢ for the ball, the math checks out.
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
Ha you got me! Good question
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 $1, the bat is only 90¢ more than the ball.
Oh, got it.
.10¢ is only 1/10 of a penny.
Yeah, disregard the decimal. It was late when I posted this.
The answer is still "other" lol.
Saw this online once
Pretty sure this was an SAT question lol
5¢ and 1.05$ I believe
