conversations.value: A laboratory needs flasks, test tubes, and safety gear to carry out its experiments. They were given a $325 budget for the month. They bought $150 worth of flasks, spent two-thirds of that amount on test tubes, and used half of the test tube cost on safety gear. How many dollars of their budget remained?

conversations.value: The laboratory spent 2 / 3 * 150 = 300 / 3 = $100 on test tubes.
  They spent a further 100 / 2 = $50 on safety gear.
  In all, they spent 150 + 100 + 50 = $300.
  Thus, 325 - 300 = $25 of the laboratory’s budget remained.
