(a) Let t be the time (in hours) since the beginning of the experiment, and let y be the amount of the substance (in kg) at time t. Write a formula relating y to t. Use exact expressions to fill in the missing parts of the formula. Do not use approximations. y = e (b) How much of the substance is left 12 hours after the beginning of the experiment? Do not round any intermediate computations, and round your answer to the nearest whole number.
