Answer: There are 9 pies that the club needed to make.
Step-by-step explanation:
Since we have given that
Number of pies = 4
Number of pieces cut from each pie = 7
So, total number of pieces they needed = 91
Number of pieces from 4 pies = [tex]4\times 7=28[/tex]
so, Number of pieces the club needed to make is given by
[tex]91-28\\\\=63[/tex]
Since each pie is cut into 7 pieces.
And number of extra pieces needed = 63
So, Number of pies would be
[tex]\dfrac{63}{7}=9[/tex]
Hence, there are 9 pies that the club needed to make.
