Initially 5 grams of salt are dissolved into 10 liters of water. Brine with concentration of salt 3 grams per liter is added at a rate of 6 liters per minute. The tank is well mixed and drained at 6 liters per minute. Let a be the amount of salt, in grams, in the solution after t minutes have elapsed. Find a formula for the incremental change in the amount of salt, Ax, in terms of the amount of salt in the solution a and the incremental change in time At. Enter At as "Deltat". 3x Ax= 18- 5 Deltat grams help (formulas) Find a formula for the amount of salt, in grams, after t minutes have elapsed. grams help (formulas) x(t) = 26-26e
