How many legs do the tables with four legs have? ** The total number of legs which the tables with four legs have is 40*4 = <<40*4=160>>160 legs
How many legs do the tables with three legs have? ** The three-legged tables have a total of 50*3 = <<50*3=150>>150 legs.
How many legs do the restaurant's tables have? ** The total number of legs that the restaurant's table have is 150+160 = <<150+160=310>>310
