If 100 attendees are expected at an event,the fixed costs total 10,000 and the variable costs are 20 per person; the registration fee per person necessary to generate enough revenue to break-even is: 100 160 140 120

To determine the registration fee per person necessary to break even, we need to calculate the total cost and set it equal to the total revenue.The total cost is the sum of the fixed costs and the variable costs. The fixed costs are given as 20 per person. Since there are 100 attendees, the total variable costs are 2,000.The total cost is 2,000 = x x \times 100 x \times 100 = 12,000 x x = \frac{12,000}{100} = 120 \ .
