To represent this problem in the form of an equation, let's assume that "x" represents the number of pages Taylor read.
Given that Reads read 30 pages, we can determine that Reads read 100 pages more than half of what Taylor read.
Half of what Taylor read is x/2, and 100 pages more than that is x/2 + 100.
So, Reads read 30 pages, which can be expressed as 30.
Therefore, the equation representing this problem in the form Px + q = r is:
30 = x/2 + 100
