Answer:
The correct answer is A. C(x)= 1,200 + 120x R(x) = 200x
Step-by-step explanation:
Costs:
Store rent = US$ 1,200
Employees salaries per hour = US$ 120
Revenue:
Sales per hour = US$ 200
Number of hours per month the store is open = x
Cost function C (x):
1,200 + 120 (x) (Store rent + Employees salaries multiplied by the total amount of hour the store is open per month)
Revenue function F (x):
200x (Sales per hour multiplied by the total amount of hour the store is open per month)
Therefore, the correct answer is A. C(x)= 1,200 + 120x R(x) = 200x
