Answer:
The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0.
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.
