In a lab experiment, the decay of a radioactive isotope is being observed. At the beginning of the first day of the experiment the mass of the substance was 1400 grams and mass was decreasing by 8% per day.

Answer:  339.3 grams

Work Shown:

y = 1400(1-0.08)^x

y = 1400(1-0.08)^17

y = 339.25097192703

y = 339.3
