<span>The durations and coverage of the manufacturer’s warranty, as well as whether or not the extended warranty overlaps with it, should be taken into consideration. The likelihood of the item needing repairs, as well as the cost of repairing it, should also be considered. Furthermore, it is helpful to consider the cost of the warranty, its relation to the cost of the item, and whether it is a full or limited warranty.

Answer:
13.57 kg
Step-by-step explanation:
Let the amount of salt in a tank be =
= 
= 0.3 kg/L
The concentration of salt coming into the tank = 0.333kg/L
We know that the concentration of salt leaving the tank should be:
amount of salt in the tank/volume of tank = y(t)/50 L
rate of change of salt = rate in - rate out
= 0.66 - 
solving the differential equation gives :
ln y = 0.66/y (t) - 0.02 t + C
Initial conditions, t= 0; y (0) = 15
then ln 15 = C
ln y =
t - 0.02t + ln 15
ln
= 0.02t
y = 15e( exp -0.02t)
the amount of salt in 5 mins will be:
y (t) = 15e(exp -0.02 (5)
= 13.57 kg
