Ascientist is studying the decay of a certain substance after being exposed to two different treatments. under treatment a, the substance continuously decays at a rate of 4% daily. under treatment b, another sample of the same substance continuously decays at a rate of 6.2% daily. a second scientist comes to record the amount remaining each day and only knows that there was initially less than 300 grams of the substance undergoing treatment a and at most 400 grams of the substance undergoing treatment b. what system of inequalities can be used to determine t, the number of days after which the remaining amount of each sample, y, in grams, is the same?
