John buys 3 different coolers.  The first one is 100 liters.  The second is 50% bigger than that and the third is half the size of the second.  How much total water can they hold? Let's think step by step and output the final answer after "####".

The second cooler is 100*.5=<<100*.5=50>>50 liters bigger than the first
So it is 100+50=<<100+50=150>>150 liters
The third is 150/2=<<150/2=75>>75 liters
So the total water they can hold is 100+150+75=<<100+150+75=325>>325 liters
#### 325
