Your textual description is perfect, but I don't agree with your equations.  To put it in a single equation, I would say:

        /------------------- Initial amount        / /------------------ Cab       / /  /---------------- Dinner      / /  /   /------------- Half (painting)     / /  /   /   /---------- Umbrella    / /  /   /   /       /--- Amount left ((X-20-25)/2)-23.75 = 42.15

Solving this for X, we find that X=\$176.80, same answer you arrived at.
