Tiffany is monitoring the decay of two radioactive compounds in test tubes at her lab. Compound A is continuously decaying at a rate of 12% and compound B is continuously decaying at a rate of 18%. Tiffany started with 30 grams of compound A and 40 grams
of compound B.
Create a system of inequalities that can be used to determine when both compounds will be less than or equal to the same mass, M.
where t is time, in weeks, PA is the initial amount of compound A, Pg is the initial amount of compound B, and r is the rate of decay.
Enter the inequalities in the field by replacing the values of PA, PA, and r.
