Five boxes of pizza cost 5 x $10 = $<<5*10=50>>50.
Ten cans of soft drinks cost 10 x $2 = $<<10*2=20>>20.
So, Robert spends $50 + $20 = $<<50+20=70>>70.
Six hamburgers cost 6 x $3 = $<<6*3=18>>18.
Thus, Teddy spends $18 + $20 = $<<18+20=38>>38.
Therefore, they spend $70 + $38 = $<<70+38=108>>108 in all.
