QUESTION A

The total number of bottles Ella collected is
[tex]50[/tex]


The number of bottles that are plastic is

[tex]19[/tex]

The percentage of bottles that are plastic is

[tex] = \frac{number \: of \: plastic \: bottles}{total \: number \: of \: bottes} \times 100\%[/tex]

[tex] = \frac{19}{50} \times 100\%[/tex]

[tex] = 19 \times 2\%[/tex]
[tex] = 38\%[/tex]

Therefore 38% of the bottles are plastic.



QUESTION B

The total number of bottles that are glass is
[tex]50 - 19 = 31[/tex]

The total number of bottles Ella collected is
[tex]50[/tex]

The percentage of bottles that is glass is
[tex] = \frac{number \: of \: glass \: bottles}{total \: number \: of \: bottles} \times 100\%[/tex]

[tex] = \frac{31}{50} \times 100\%[/tex]

[tex] = 31 \times 2\%[/tex]
[tex] = 62\%[/tex]

Therefore 62% of the bottles are glass
