Answer:
8.5 bags are needed.
Step-by-step explanation:
Given : Number of bags needed [tex]B=x(2x+7)+3(2x+7)+(x+4)[/tex]
[tex](2x + 7) = 4[/tex]
To Find : how many bags he needs?
Solution :
[tex](2x + 7) = 4[/tex]
[tex]2x=-3[/tex]
[tex]x=-\frac{3}{2}[/tex]
Now we are given that Number of bags needed [tex]B=x(2x+7)+3(2x+7)+(x+4)[/tex]
Substitute the value of x
[tex]B=(\frac{-3}{2})(2(\frac{-3}{2})+7)+3(2(\frac{-3}{2})+7)+((\frac{-3}{2})+4)[/tex]
[tex]B=8.5[/tex]
Hence 8.5 bags are needed.
