00:00:01.640 --> 00:00:07.760
The original price of this car is 8999 pounds.
00:00:09.080 --> 00:00:15.400
And we can see there’s a poster behind the car that says sale 1100 pounds off.
00:00:17.120 --> 00:00:19.360
What is the sale price of the car?
00:00:21.280 --> 00:00:24.360
We can see this problem is all about a car that’s being sold.
00:00:25.200 --> 00:00:27.480
And we need to think about two prices.
00:00:28.760 --> 00:00:33.680
The original price is the price of the car before there was a sale on.
00:00:34.920 --> 00:00:36.800
And we’re given this price.
00:00:36.800 --> 00:00:39.960
It was 8999 pounds.
00:00:41.120 --> 00:00:45.960
If we sketch a bar model, we can use this bar to represent the original price.
00:00:46.960 --> 00:00:49.240
But there’s another price that we need to think about.
00:00:49.760 --> 00:00:56.040
And that’s the sale price, the price of the car after some money has been taken off.
00:00:57.160 --> 00:01:00.000
Now at the moment, we don’t know what the sale price it is.
00:01:01.240 --> 00:01:09.120
A mistake that some people might make is to look at the sign and think that the car is now worth 1100 pounds.
00:01:10.520 --> 00:01:12.640
But look carefully at the sign.
00:01:12.640 --> 00:01:16.120
There’s a three-letter word that shows us that this is not the case.
00:01:17.080 --> 00:01:20.680
The car has 1100 pounds off.
00:01:21.480 --> 00:01:31.880
In other words, 1100 pounds is the amount of money we need to take away from 8999 pounds to find the sale price.
00:01:33.000 --> 00:01:41.240
So the calculation we need to work out to find the answer is 8999 take away 1100.
00:01:42.600 --> 00:01:53.480
Because we’re taking away 1100, we will expect the number of thousands to decrease by one and the number of one hundreds to decrease by one.
00:01:54.440 --> 00:01:57.160
The car now costs seven thousand and something.
00:01:58.480 --> 00:02:06.880
And instead of 7999, we have one less hundred, 7899.
00:02:08.080 --> 00:02:13.600
So to find the answer, we recognized that we needed to use the price on the sign to help us.
00:02:14.800 --> 00:02:21.280
We knew the original price or the starting price of the car was 8999 pounds.
00:02:22.120 --> 00:02:30.840
And the sign showed us that 1100 pounds had been taken off the original price to give a sale price.
00:02:31.720 --> 00:02:39.280
So to find the answer, we knew that we had to take away 1100 from 8999.
00:02:40.520 --> 00:02:45.480
This meant that the thousands digit and the hundreds digit decreased by one.
00:02:47.120 --> 00:02:54.800
The new price or the sale price of the car is 7899 pounds.
