A bat and a ball cost one dollar and ten cents in total. The bat costs a dollar more than the ball. How much does the ball cost? @Kevin LOL have lots of fun you wont EVER figure it out.

hey dude

:D

OpenStudy (kevin):

I know the answer is 10 cent, but I have difficulty on how to write the answer way

OpenStudy (brainzonly):

LOL WRONG

OpenStudy (brainzonly):

XD This is SO funny :D The Answer: The ball costs 5 cents. Explanation: When you read the math problem, you probably saw that the bat and the ball cost a dollar and ten cents in total and when you processed the new information that the bat is a dollar more than the ball, your brain jumped to the conclusion that the ball was ten cents without actually doing the math. But the mistake there is that when you actually do the math, the difference between $1 and 10 cents is 90 cents, not $1. If you take a moment to actually do the math, the only way for the bat to be a dollar more than the ball AND the total cost to equal $1.10 is for the baseball bat to cost $1.05 and the ball to cost 5 cents.
