Question

What's the best way I can determine the best answer?

Answer 1

A. 10%

Step-by-step explanation:

The total number of sandwiches sold = 3000

The number of sandwiches on a Sesame bun with Swiss cheese = 300

Express this as a percentage:

`\begin{gathered} =(300)/(3000)*100 \\ =(1)/(10)*100 \\ =10\% \end{gathered}`

The correct choice is A.
