ANSWER
The percentage of cans that are recycled is
[tex]65\%[/tex]
EXPLANATION
The number number of cans that are recycled is
[tex]13[/tex]
The total number of cans is
[tex]20[/tex]
The percentage of cans that are recycled is
[tex] = \frac{number \: of \: cans \: recycled}{total \: number \: of \: cans} \times 100\%[/tex]
[tex] = \frac{13}{20} \times 100\%[/tex]
We simplify to obtain,
[tex] = \frac{13}{1} \times 5\%[/tex]
This will give us,
[tex] = 65\%[/tex]
