At a parking garage, parking costs \( \$ 4 \) for ...

At a parking garage, parking costs \( \$ 4 \) for up to one hour. After that, it costs \( \$ 2.50 \) for each additional hour or fraction thereof. Write a function to represent the cost of parking for \( x \) hours. Then use the function to find the cost of parking for \( 5 \) hours and \( 23 \) minutes. 

\( f ( x ) = 4 + 2.5 [ x ] - 1 ; \$ 11.50 \) 

\( f ( x ) = 4 + [ 2.5 x ] ; \$ 10.50 \) 

\( f ( x ) = 2.5 [ 4 x ] - 1 ; \$ 10.50\) 

None of the other answers are correct 

\( f ( x ) = 4 [ 2.5 x ] ; \$ 8.50\)
