Answer:
40% decrease
Step-by-step explanation:
First, let's find the value decrease of the item from yesterday to today
$65 - $39 = $26
That means that $65 was 100% of the price and decreasing it by 26 gets us to 39
We need to find the percentage of 39 in 65
39/65 = 0.6 or 60%
If 39 is 60% of 65, then there was a 40% decrease form 100%
To check we can calculate the percentage of 26 in 65:
26/65 = 40%
There was a 40% decrease

The answer is: <span>40,000(1.12)(1.10)
Or 4 more understanding: 12% of £40000
</span>1%= 400, therefore, 12%= 4800.
In January, the value was £44800.
10% of this is £448.
Add £448 to £44800, giving you £45, 248
The mean is the average.
To solve for the average we add all the numbers up and divide by how many numbers there are.
21, 23, 25, 25, 26, 28, 28, 28, 31, 33.
268 total, now divide by how many numbers there are.
268/10
Your mean is 26.8
