conversations.value: Axel bought an aquarium that was marked down 50% from an original price of $120. But he also paid additional sales tax equal to 5% of the reduced price. What was the total cost of the aquarium?
  Give me a solution to this problem

conversations.value: The aquarium was bought for $120 x 50/100 = $60 less.
  So the marked down price of the aquarium was $120 - $60 = $60.
  Axel paid $60 x 5/100 = $3 additional for the sales tax.
  Therefore, the total cost of the aquarium was $60 + $3 = $63.
