Both Sam and Sylvia work at a bookstore. During a sale, Sam sold 15 percent more books

than Sylvia. If Sam sold 69 books, how many books did Sylvia sell?
A. 60 C. 54
B. 58 D. 50

B

let the number of books Sylvia sold be x

then 1.15x = 69
x = 69/1.15 = 60

To find out how many books Sylvia sold, we need to calculate 15% less than the number of books Sam sold.

Step 1: Calculate 15% of the number of books Sam sold.
15% of 69 books = (15/100) * 69 = 0.15 * 69 = 10.35.

Step 2: Subtract the result from the number of books Sam sold to find out how many books Sylvia sold.
69 books - 10.35 books = 58.65 books.

Since we can't have a fraction of a book in this case, the closest option is B. 58.
