Apublishing company is going to have 24000 books printed. there are between 3 and 4 books out of every 3000 printed that will have a printing error. at this rate, which number could be the number of books that will have a printing error in the 24000

Given:

24,000 books

Between 3 and 4 books will have a printing error in every 3000 printed books

Find: in the 24000 books, the total number of books that will have a printing error

Solution:

Based from the given, we need to know how many sets of 3000 we

have in the 24000 books so:

24000 / 3000 = 8

Now, in each set of 3000 we have between 3 and 4 errors and we have 8 sets of 3000 books:

minimum errors 3 * 8 = 24

maximum errors 4 * 8 = 32

Therefore, at this rate, the number of books that will have a printing error in the 24000

will be between 24 and 32 or 24 < E < 32.

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
