[EXC]

If a bat and a ball together cost £1.10 and the bat alone cost £1 more than the ball, how much is the ball?

10p is this too easy or is there a catch????

Yep---that means the bat cost only 90p more than the ball

Answer-5p

Re: If a bat...

ie--Algebraic equations

Equation A--Bat + Ball =110
Equation B--Bat-Ball =100 therefore Bat=(100 + Ball)

Subsitute B in A gives
(100+Ball) + Ball = 110
therefore 2 Balls = 110-100
therfore ball = 5

Where does it state 2 balls????

ie

Equation A--Bat + Ball =110
Equation B--Bat-Ball =100 therefore Bat=(100 + Ball)

Subsitute B in A gives
(100+Ball) + Ball = 110
therefore 2 Balls = 110-100
therfore ball = 5

The 2 balls is only the algebra Tutts

Trust Turbo 'The Human Calculator' to get it right.

If my teachers had explained it like Turbs, it would'nt have taken me 50 years + to get it

i still dont get it

still it takes brains to be fik.

Re: If a bat...

My non algebra brain does the calculation differently, but still comes up with the same answer.

We know the bat is £1 more. so remove the £1 from the equation and we are left with 10p. Divide the 10p by 2 and we have 5p. So the bat costs £1.05 and the ball 5p.

More simplistic I know, but then so is my brain.

Re: If a bat...

where did the 2 balls come from?

if it costs 110 for the 2 bits and there are only 2 bits... where did the second lot come from??

bat is £1, all thats left is the ball so that is 10p.. i went to the 5p less that 10p school of math.

Re: If a bat...

I don't know where the 2 balls come from, but, the bat is £1 more than the ball, so if the ball is 10p, then the bat is only 90p more than the ball. You take the £1 away from the equation cause you know the bat has to be a £1 more than the ball, then you divide whats left and you get a ball at 5p.

So the ball is 5p
The bat is £1.05
That equals £1.10

Meaning the bat is £1 more than the ball.

Re: If a bat...

Subsitute B in A gives
(100+Ball) + Ball = 110
therefore 2 Balls = 110-100
therfore ball = 5

From Turbs post - very confusing
