After that, there were 18 fish in the tank altogether. How many clownfish were there in the tank at first? My work: # of clownfish = C # of anglefish = A [1] A tank had 20 clownfish and angelfish => C + A = 20 [2] 4 clownfish were sold and some angelfish were added to the tank such that the number of angelfish increased by 50%. After that, there were 18 fish in the tank altogether. => C - 4 + (A + .5A) = 18 My question is in [2]. I'm guessing A is the total of anglefish, but we have to add .5A more because of a 50% increase? I'm I correct for what I did in [2]?
