5. A tank contains 100 gal of water and 50 lbs of salt. Water containing a salt concentration of (1 + sin(t)) lbs/gal flows into the tank at a rate of 2 gal/min, and the mixture in the tank flows out at the same rate. (a) Assuming perfect and instantaneous mixing, write down the IVP that models the amount of salt in the tank, q(t), as a function of the time, t, in minutes.
