Abusiness 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 equation can be solved to determine the break-even point if x represents the number of hours per month the store is open? 200x – 120x = 1,200 120x + 200x = 1,200 200x + 1,200 = 120x 120x – 1,200 = 200x
