A $+1\mathrm{.}512\%$ grade meets a $-1\mathrm{.}785\%$ grade at PVI Station $31+50,$ elevation $562\mathrm{.}00.$ The Equal Tangent Vertical curve $=700$ feet. Calculate the elevations on the vertical curve at full stations. make sure to calculate the gradient elevations but you need to also calculate the elevations on the curve. and include the table that inlsudes he station, gradient elevation, tangent offset, and vertical curve calculation
