Answer:
x<8
Step-by-step explanation:
i don't think the question was complete, i cannot make an inequality with just the information given.
Set up a ratio to find the number of pages read in 80 minutes:
40 pages/ 50 minutes = x pages/ 80 minutes
Cross multiply:
50x = 3200
Divide both sides by 50:
X = 3200/50
X = 64
He will read 64 pages in 80 minutes.
200 -64 = 136
There will be 136 pages left.
Firstly, we will find smallest value and largest value
smallest value is in 2009
and smallest value is 3
largest value is in 2010
and largest value is 12
So, percentage change will be greatest between 2009 to 2010
now, we can find percentage change
