Answer 1

Let x be the number of hours that we rent the bike.

The total cost for City Saddles is:

$2x+16$

The total cost for Park Bikes is:

$3.5x+7$

The cost will be equal when:

$2x+16=3.5x+7$

Solving for x we have:

$\begin{gathered} 2x+16=3.5x+7 \\ 3.5x-2x=16-7 \\ 1.5x=9 \\ x=\frac{9}{1.5} \\ x=6 \end{gathered}$

Therefore, after 6 hours the cost will be the same, so the answer is A.
