This is a trick question: a bat and a ball cost $1.10 together. If the bat costs $1 more than the ball, then how much does the ball cost? Here's the video I got this from: https://www.youtube.com/watch?v=JiTz2i4VHFw

ball = # 5c#

bat + ball = 110 (1)

bat=ball + 100 (2)

so from (1):

bat = 110 - ball

subs this into (2):

110 - ball = ball + 100

10 = 2 x ball

ball = 10/2 = 5c

So from (1) bat must be 110 - 5 = 105c

i.e $1 more.

I didn't even watch the video!
