The question is incomplete. Here is the complete question:
During ski season,the owner of ski shop has determined that the number of customers in a day is greater than or equal to 50 more then the temperature(Fahrenheit)
. Write an inequality for the problem and determine the constraints on the variables.
Answer:

Step-by-step explanation:
Let the number of customers be 'N' and the temperature in Fahrenheit be 'T'.
Given:
Number of customers is related to temperature in Fahrenheit as:
Number of customers is greater than or equal to 50 more than the temperature in Fahrenheit. This means,

Now, since 'N' represents number of customers and number can never be a negative quantity. So, the only constraint for this inequality is that the number of customers must be greater than or equal to 0.
So, 
The answer is A because the rate of change is 7.
You can find this by writing it from standard form to slope intercept (y = mx+b).
B is 6, C is 5, and D is also 5 (all lower than 7)
The answer is probably 50 ok
