P (x) = 90(1 + 1.5x) / 1 + 0.5x

P = number of fish
x = number of months since the fish were placed in the aquarium

Six months after the fish are first placed in the aquarium, what is the total number of fish?

225

anonymous · Answer

P(6) = 90(1+1.5*6)/(1+.5*6) = 225

can you please show me how you got that?

anonymous · Answer

Ok, sure.
Since x = the number of months, and you are finding the total number of fish after 6 months, then you plug in 6 for x.
So refer to my previous answer starting with P(6) for the mathematical method.
Did you need something more specific?
I typed (90*(1+1.5*6))/(1+.5*6) into my calculator to account for order of operations.
