A gumball machine has red, green, and blue gumballs. The machine has half as many blue gumballs as red gumballs. For each blue gumball, the machine has 4 times as many green gumballs. If the machine has 16 red gumballs how many gumballs are in the machine?
There are 16/2=<<16/2=8>>8 blue gumballs.
There are 8*4=<<8*4=32>>32 green gumballs.
There are 16+32+8=<<16+32+8=56>>56 total gumballs.
