Answer:

\large \boxed{\text{A) } \dfrac{6}{x} = \dfrac{9}{\$7.74}}

Step-by-step explanation:

9 pencils cost $7.74

6 pencils cost x

The ratios are  

\dfrac{9}{6} = \dfrac{\$7.74}{x}

According to the alternendo property,

\dfrac{9}{6} = \dfrac{\$7.74}{x} \Rightarrow \dfrac{9}{\$7.74} = \dfrac{6}{x}\\\\\text{The correct answer is $\large \boxed{\mathbf{ \dfrac{6}{x} = \dfrac{9}{\$7.74}}}$}
