517284 books have been sold to date.
Step-by-step explanation:
Given,
Copies sold in first month = 41900
This represents 8.1% of copies sold to date.
Let,
x be the number of copies that have been sold to date.
8.1% of x = 41900

Dividing both sides by 0.081

Rounding off to nearest whole number
x = 517284
517284 books have been sold to date.

Step-by-step explanation:
We know that
At sea level, the height is 0 and
the pressure is 98 kilopascals
At 1000 ft, the height is 1000 and
the pressure <span>decreases about 11.41%
</span>i(100%-11.41%)/100----> (0.8859)
therefore
1) at 1000 ft--------> the pressure is 98*(0.8859)----------> 86.82 kilopascals
2) at 2000 ft--------> the pressure is 86.82*(0.8859)-------> 76.91 kilopascals
3) at 3000 ft--------> the pressure is 76.91*(0.8859)-------> 68.14 kilopascals
4) at 4000 ft---------> the pressure is 68.14*(0.8859)-------> 60.36 kilopascals
the answer is
<span>The pressure at an altitude of 4000 m is about </span>60.36 kilopascals
