A. how many feet of boards should he buy? explain.
B. If you can only buy 8-foot boards, how many should he buy?explain

Answer :

A. 95 feet
B. 12, because that would get you 96 feet of board, and if you only got 11, then you would only have 88 feet of boards which is not enough.

Answer with explanation:

Number of boards need by corey =24

Length of each board is [tex]47 \frac{1}{2}\\\\=\frac{95}{2}[/tex]

Length in inches of board that corey should buy

          [tex]\frac{95}{2}\times 24\\\\=95*12\\\\=1140[/tex]inches

1 foot=12 inches

[tex]\frac{1}{12} \text{foot}=1\text{inches}\\\\\frac{1140}{12} \text{foot}=1140\text{inches}\\\\95\text{foot}=1140\text{inches}[/tex]

So, Length in feet of board =95 foot

B.

Length of each board = 8 foot

Total Length in feet of board =95 foot

So, number of boards that corey should buy

              [tex]\frac{95}{8}\\\\=11\frac{7}{8}[/tex]

=Approximately 12 Boards
