A tаnk cоntаins 50 gаllоns оf a solution composed of 90% water and 10% juice. A second solution containing 50% water and 50% juice is added to the tank at a rate of 4 gallons per minute. The tank is being drained at a rate of 5 gallons per minute. The solution in the tank is stirred constantly. How much juice is in the tank after 10 minutes. Let j be the number of gallons in the tank at any time t. Write a differential equation in terms of j and t, and solve for j at time t = 10. HINT: the number of gallons of solution at any time t is 50-t (loses 1 gallon per minute). Click 'True' when done
