Let's calculate.
:49:05
A bus ticket costs 20.5 yuan.
:49:09
Multiply this by three.
:49:11
Equals 61 .5 yuan.
:49:19
We still need 52.5.
:49:22
The man at the factory told us...
:49:25
by moving 1 0,000 bricks,
we make 40 yuan.
:49:28
We need 52.5.
:49:31
How many bricks
do we have to move?
:49:33
- Raise your hand.
- Let me do it.
:49:38
Jiao Jie, you do it.
:49:56
You got it wrong.
:49:59
250.
:50:05
Check it again.
:50:08
It should be 250 yuan,
not 2.5 yuan.
:50:12
You missed the decimal point.
:50:23
It's done.
:50:30
Moving 1 0,000 bricks
earns 40 yuan.
:50:34
52 bricks times 1 0,000
divided by 40.
:50:40
That substitute is not bad.
She can teach mathematics, too.
:50:47
1 30,000 bricks?
That many?
:50:49
Sure there isn't an extra zero?
:50:52
We can't move that much.
:50:56
Last time was already hard!
:50:58
Let's calculate the time.
