A scientist obtained a sample that contained 80 grams of radioactive Barium-122 that decays exponentially over time. The amount of Barius-122 that remained in the sample at observed times is shown in the table.
If the radioactive decay continues at the same rate, which is closest to the amount of the sample of Barium-122 remaining at 5 minutes?

Use regression to decide which is closest to the mass at 5 minutes.
