Question

A bat and a ball together cost $1.10. The cost of the bat is $1.00 more than the ball.
What is the cost of the ball? ​

Answer 1

$0.10 is the cost of the ball.

Answer 2

Ball = y

price of bat = y + 1 = x [ it costs 1$ more than ball ]

Now ,

x + y = 1.10

( y+1 ) + y = 1.10

2y + 1 = 1.10

2y = 0.10

y = $ 0.05
