For this case, the first thing we must do is define a variable.
We have then:
x: additional amount of weight that Li can add.
We write now the inequality that represents the problem.
We have then:
Answer:
An inequality that can be used to determine how much more weight can be added to the suitcase without going over the 50-pound weight limit is:

Answer:
After 22 seconds the projectile reach its maximum height of 4,840 units
Step-by-step explanation:
we have
This is a vertical parabola downward (because the leading coefficient is negative)
The vertex is a maximum
Find out the coordinates of the vertex
Convert the quadratic equation in vertex form
Factor -10
Complete the square
Rewrite as perfect squares
The vertex is the point (22,4,840)
therefore
After 22 seconds the projectile reach its maximum height of 4,840 units
