Option A: 
is the equation.
Explanation:
Let x represents the number of hours per month the store is open.
It is given that the the monthly rent(expense) = $1200
Also, the employee salary for each hour(expense) = $120x
Thus, the total expense C(x) is 
It is also given that the income per hour(revenue) is $200x
Thus, the revenue function R(x) is 
The break - even point is given by
Total expense = Revenue
Thus, is the equation.
Hence, Option A is the correct answer.

Answer: the greatest number of courses for which miranda can register is 2
Step-by-step explanation:
Let x represent the number of courses for which Miranda can register.
If her college charges a $90 registration fee for the term plus $475 per course, it means that the total amount that the college charges for x courses would be
475x + 90
Miranda’s financial aid stipulates that her tuition not exceed $1200(it must be at most $1200). This means that
475x + 90 ≤ 1200
475x ≤ 1200 - 90
475x ≤ 1110
x ≤ 1110/475
x ≤ 2.34
