What is the sum of the two highest total purchase prices?
{"Cash paid for acquisition": {"Trek": 11723, "Electrostatic Product Line": 3000, "LumaSense": 94946, "Total": 109669}, "Less cash acquired": {"Trek": -5651, "Electrostatic Product Line": "\u2014", "LumaSense": -10262, "Total": -15913}, "Total purchase price": {"Trek": 6072, "Electrostatic Product Line": 3000, "LumaSense": 84684, "Total": 93756}}
total_price_luma = df["Total purchase price"]["LumaSense"]
total_price_trek = df["Total purchase price"]["Trek"]
answer = max(total_price_luma, total_price_trek) + min(total_price_luma, total_price_trek)
