<h2>Solving the Question</h2>

In this case, we're given the following information:

Mother = $9
Grandmother = $1 per mile
Isabelle walks <em>x</em> miles, mother pledge = grandmother pledge

The mother's donation of $9 will not change <em>no matter how many miles Isabelle has walked</em>, so if both the mother's and grandmother's donations are equal, they must each owe 9$.

<h2>Answer</h2>

Each donor owes $9.
