Answer:
x = 3
Step-by-step explanation:
Mathematically, the mean is the sum of the numbers divided by the count of the numbers
The count of the numbers is 5
Thus;
( 4 + 8 + 9 + x + 2x)/5 = 6
(21 + 3x)/5 = 6
21 + 3x = 6(5)
21 + 3x = 30
3x = 30-21
3x = 9
x = 9/3
x = 3
His total load is 4*125 + 2*75 + 2*50, which is 750
now, is that 750 95% of 800?
well 95% of anything is 95/100 * anything
thus, 95% of 800 is 95/100 * 800 or 0.95 * 800
now, is that less than more or equals to 750? if it's, then he's golden, because his load is less or equals to 95% of 800, if not, then he needs to cut down some
