please help (:

Problem 1 A container holds 100 L of salt water with a concentration of 0.5 kg/L. Starting at time t = 0 minutes, salt water with a concentration of 3 kg/L is added to the container at a rate of 5 L/min. (a) How much salt (in kg) is in the container at t = 0? (b) Starting at t = 0 minutes, salt water is drained from the container at a rate of 5 L/min. Find the concentration (kg/ L) of the solution in the tank after 10 minutes have passed. (c) Starting at if: 0 minutes, salt water is drained from the container at a rate of 10 L/min. Find the concentration (kg/L) of the solution in the tank after 10 minutes have passed
