Option B is the answer - What were the different prices of the books at the bookstore?

Explanation:

Statistical information collection is defined as a collection of, organization of and interpretation of numerical data. These information helps in drawing conclusions about a set of data.

So, option first does not give many answers or data. This question can have one or two answers only. Similarly, option third can have only two answers(yes or no). But the second option can have hundreds of answers. Hence, it can collect a lot of data and draw some conclusion about it.

step-by-step explanation:

so first find out how much each is worth.

quarter= 25 cents

dime= 10 cents

pennies= 1 cent

then multiply each by how much each is worth.

200                     150                   300

x                         x                     x   1

  25                       10              

                                  300

1000                     1500

+                          

4000                                      

5000                                  

then count 2 from the back and add a period.

$50.00

$15.00

$3.00
