The mass of a substance, which follows a continuous exponential growth model, is being studied in a lab. The doubling time for this substance was observed to
be 18 hours. There were 95.1 mg of the substance present at the beginning of the study.
(a) Let i be the time (in hours) since the beginning of the study, and let
y be the amount of the substance at time 1.
Write a formula relating y to t.
Use exact expressions to fill in the missing parts of the formula.
Do not use approximations.
