We have the follow ratio: 



number of gallons of pool # 1       number of gallons of pool # 2
---------------------------    =   -------------------------------
    depth of pool # 1                     depth of pool # 2



Plug in the given information


Multiply both sides by x


Multiply both sides by 6


Multiply


Divide both sides by 10000


Divide


So a pool that is 7.5 feet deep will hold 12,500 gallons of water
