A tower is made out of 4 blue blocks, twice as many yellow blocks, and an unknown number of red blocks. If there are 32 blocks in the tower in total, how many red blocks are there?

How many yellow blocks are in the tower? ** There are 4*2 = <<4*2=8>>8 yellow blocks in the tower.
How many red blocks are in the tower? ** There are 32-4-8 = <<32-4-8=20>>20 red blocks in the tower.
