To find a pattern, we can observe that the number of bookcases is increasing by a factor of 3 each time, and the number of screws needed is increasing by a factor of 4 each time.
Based on this pattern, if 36 screws are needed for 3 bookcases, then for 8 bookcases, we can calculate:
Number of bookcases: 8
Number of screws per bookcase: 36 / 3 = 12
So, the total number of screws needed for 8 bookcases would be:
12 screws/bookcase * 8 bookcases = 96 screws
Therefore, 96 screws are needed for 8 bookcases.
Based on this pattern, if 36 screws are needed for 3 bookcases, then for 8 bookcases, we can calculate:
Number of bookcases: 8
Number of screws per bookcase: 36 / 3 = 12
So, the total number of screws needed for 8 bookcases would be:
12 screws/bookcase * 8 bookcases = 96 screws
Therefore, 96 screws are needed for 8 bookcases.
Which is the rule for the pattern?
