tricky question. Moreover, if you use the plugin numbers strategy is time-consuming and prone of errors.

Follow step by step what the prompt says

each flower cost her \(\frac{d}{c}\) dollars

the selling price of each flower is \(\frac{c}{d}\) dollars. Since, overall she made a profit, the selling price per flower must be greater than the cost per flower

we have \(\frac{c}{d} > \frac{d}{c}\).

After manipulation, in the end is \(1 > \frac{d}{c}\)

B is the answer.

\(\frac{c}{d} > \frac{d}{c}\)

Cross multiply

\(c^2 > d^2\)

square both sides

\(c > d\)

\(1 > \frac{d}{c}\)


Hope this helps
