An equal tangent sag vertical curve is 600 ft long (i.e. 6 stations). The elevation of PVC is 1000 ft. The initial grade is -0.035 ft/ft (-3.5%) and the final grade is +0.005 ft/ft (+0.5%). What is the elevation of a point that is 350 ft (3.5 stations) from PVC?

A) 1005.42 ft

B)991.83 ft

C) 991.01 ft

D) 996.83 ft
