Call the price of the bike before mark up 'x', then we have:

x + 0.25x = 210
1.25x = 210
x = 168

Therefore, the bike cost $168 before 25% price increase.

Can you please help me with this problem

vagabundo [1.1K]

$\bf \begin{cases}
\textit{area of a circle}=\pi r^2
\\ \quad \\
circumference=2\pi r
\end{cases}
\\ \quad \\

12.56=\pi r^2\implies \cfrac{12.56}{\pi }=r^2\implies \sqrt{\cfrac{12.56}{\pi }}=\boxed{r}
\\ \quad \\
thus
\\ \quad \\
circumference=2\pi \boxed{r}\implies 2\pi \boxed{\sqrt{\cfrac{12.56}{\pi }}}$
