Answer: 49 books
Step-by-step explanation:
Number of books read by Manuel this year = 35
Increment in reading rate = 40%
Therefore, we now find 40% of 35 and add it to 35 to know the number of books he had read
Number of books read = 40% of 35
= 40/100 x 35
= 14 books
Total number of books read = 35 + 14
= 49 books
