Answer:
Mrs. Baker
Number of books Mrs. Baker bought in all is:
= 50 books
Explanation:
No. of paperback books bought = 12
Percentage of paperback books bought = 24%
Therefore, total number of books bought = 12/24%
= 50 books
Proof:
24% of 50 = 12
and 12/50 = 0.24 = 24%
This shows that we can obtain the total number of books that Mrs Baker bought by using the proportion of the paperback books. Since she bought 12 paperback books and the proportion of paperback to the total books is 24%, it implies that she bought 50 (12/0.24) books.
