Answer:
To earn profit : 50 < c < 150 is the expression that best expresses this situation.
Step-by-step explanation:
The minimum number of cattle Mr. Riley can raise = 50
The maximum number of cattle Mr. Riley can raise = 150
Let the number of cattle is represented as c.
So, according to the question:
To make profit,
Number of cattle > 50
and Number of cattle < 150
or, c > 50
and c < 150
Hence, on combining both the expressions, we get
To earn profit 50 < c < 150 is the expression that best expresses this situation.
