$(15$ pts$)$ Using the mass diagram given below, determine the total overhaul cost if the free haul is $700ft$ and the overhat cost is $$10$ per cubic yard station. Stations of the free haut lines are $1+80$ and $8+80$ and $10+20$ and $17+20.($Note that the ordinate is zero at station $9+60$ and other ordinates are given below$)$
