Answer:

Step-by-step explanation:
Let x be the number of adults and y be the number of campers.
There are rooms for 450 people, so
x+y≤450.
Each adult costs $7, then x adults cost $7x.
Each camper costs $4, then y campers cost $4y.
There is a maximum budget of $1,150, so
7x+4y≤1,150
Hence, you get the system of two inequalities:

We are given in this item that the elevation required for flying a plane is 500 m or higher. This concept can also be expressed as, ''elevation must be at least 500m''. Further, this can be expressed as,
''elevation should be greater than or equal to 500m''
If this is to be translated to the mathematical inequality, the answer would be,
h ≥ 500 m
