The required inequality is $20x+10y\le 80,000$.

Work Step by Step

We know that the number of water bottles and medical packets is $x\text{ and }y$, respectively. Then, according to the statement given, a plane can carry a maximum weight of $80,000$ pounds. Therefore, the required inequality will be as given below: $20x+10y\le 80,000$ Thus, the required equation is $20x+10y\le 80,000$.
