Answer: 50 pages
Step-by-step explanation:
From the question, we are informed that Desmond has already read 12 pages, and he knows he can read 19 more pages during every additional hour he spends reading. This can be expressed as:
= 12 + 19x
where x = number of extra hours
Since he spent 2 hours of reading, the number of pages read will be:
= 12 + 19x
= 12 + 19(2)
= 12 + 38
= 50 pages
