Respuesta :
we know that
there are [tex]80[/tex] rubber bands per bag
so
by proportion
Find the number of rubber bands in [tex]4[/tex] bags
[tex]\frac{80}{1} \frac{rubber\ bands}{bag} =\frac{x}{4} \frac{rubber\ bands}{bags}\\ \\x=80*4\\ \\x=320\ rubber\ bands[/tex]
therefore
the answer is
[tex]320\ rubber\ bands[/tex]
The number of total rubber bands he buys is 320.
Given that,
The child purchase 4 bags of rubber bands for making into the bracelets.
And, there are 80 rubber bands per bag
So, the number of total rubber bands he buys is
= 4 bags of rubber bands × 80 rubber bands per bag
= 320 rubber bands
Therefore we can conclude that the number of total rubber bands he buys is 320.
