Answer: [tex]30 \%[/tex] of the burgers were well done
Step-by-step explanation:
Firstly, we are told that a total of 50 burgers were served at Kayla's Burgers, this represents the [tex]100 \%[/tex].
In additon, we are told 15 of that burgers were cooked well done and we need to know which percentage they represent. This can be calculated by the Rule of Three as follows:
[tex]50 burgers[/tex]-----[tex]100 \%[/tex]
[tex]15 burgers[/tex]-----[tex]X[/tex]
Then:
[tex]X=\frac{(15 burgers)(100 \%)}{50 burgers}[/tex]
[tex]X=30 \%[/tex] This means that [tex]30 \%[/tex] of the burgers were well done
