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?
How much did the laboratory spend on test tubes? ** The laboratory spent 2 / 3 * 150 = 300 / 3 = $<<2/3*150=100>>100 on test tubes.
How much did the laboratory spend on safety gear? ** They spent a further 100 / 2 = $<<100/2=50>>50 on safety gear.
How much did the laboratory spend in total? ** In all, they spent 150 + 100 + 50 = $<<150+100+50=300>>300.
How much of the laboratory’s budget remained? ** Thus, 325 - 300 = $<<325-300=25>>25 of the laboratory’s budget remained.
