A pet store owner pays $1,000 per month in rent and a total of $100 per hour in employee salary for each hour the store is open. On average, the store brings in $300 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) = 1,000+100 R(x) = 300x

C ( x ) = 1,000+100 R(x) = 3 00 x

C(x) = 300x R(x) = 1,000+100

C(x) = 300x R(x) = 1,000+100x
