$\boxed{Total \ cost=\$ 30}$

<h2>Explanation:</h2>

We know some facts:

There is a toll plaza every 12 1/2 miles along a 300 mile road.
At each toll plaza drivers must pay $1.25.

First of all, we have to convert the mixed fraction into improper fraction:

$12\frac{1}{2}=12+\frac{1}{2}=12.5miles$

Next, let's calculate the total number of toll plaza along the way:

$\frac{300}{12.5}=24 \ toll \ plaza \ in \ total$

As in every toll plaza, the driver must pay $1.25 then the total cost to drive the whole length of the road is:

$Total \ cost=24(1.25) \\ \\ \boxed{Total \ cost=\$ 30}$
