a business owner pays $1,200 per month in rent and a total of $120 per hour in employee salary for each hour the store is open. on average, the store brings in $200 in net sales per hour. which equations can be solved to determine the break - even point if c(x) represents the cost function, r(x) represents the revenue function, and x the number of hours per month the store is open? c(x)=1,200 + 120x; r(x)=200x c(x)=1,200 + 120; r(x)=200x c(x)=200x; r(x)=1,200 + 120x c(x)=200x; r(x)=1,200 + 120

Answer

Explanation:

Step1: Define cost function

The fixed - cost is the monthly rent of $1200 and the variable cost is $120 per hour of operation. So the cost function $C(x)$ is the sum of the fixed cost and the variable cost, $C(x)=1200 + 120x$.

Step2: Define revenue function

The store brings in $200 in net - sales per hour. So the revenue function $R(x)$ is the amount per hour times the number of hours, $R(x)=200x$.

Answer:

A. $C(x)=1200 + 120x; R(x)=200x$
