some are yellow and some are green.
John chooses a chip at random, records the color, and places it back in the bag.
John has recorded 57 yellow chips and 19 green chips.

Use proportion.
[tex]\frac{19}{76}=\frac{x}{100}[/tex]
[tex]1900 = 76x[/tex]
divide both sides by 76
[tex]\frac{1900}{76}=\frac{76x}{76} \\ \\\\\frac{1900}{76}=x[/tex]
[tex]25 = x[/tex]
