(a) A 50 L tank initially contains 2 L of salt water at a concentration of 5 g/L. Salt water at a concentration of 4 g/L is being pumped in at 2 L/min and the mixture is leaving at 1 L/min. Write down BUT DO NOT SOLVE the initial value problem whose solution gives the amount of salt at time . (b) Given the initial value problem # - ty -1 with 7(1) – 0 Use Euler's Method with step size /-0.5 and two steps to approximate y(2), Make sure your work is neat and your approximations for y(1.5) and 7(2) are clearly labeled. Simplify.
