can you please explan D for me. if my estimated total cost for 7,500 visits is $302,500 to get my average cost per visit is $302,500/7,500=40.33333. how did they get the answer 24.2?

10,000 Number of visits Utilities Wages and benefits $220,000 $5,000 $30,000 Medical supplies Administrative supplies $2,500 $50,000 $10,000 Rent Depreciation Assume that all costs are fixed except supplies costs, which are variable. a. What is the clinic's underlying cost structure? b. What are the clinic's expected total costs? . What are the clinic's estimated total costs at 7,500 visits? At 12,500 visits? 5. What is the average cost per visit at 7,500, 10,000, and 12,500 visits? Answer 1 of 1 Done a) Cost of Medical supplies = $50,000 Cost of Administrative supplies = $10,000 Cost of total supplies - Cost of Medical supplies + Cost of Administrative supplies = 50,000 + 10,000 = $60,000 Number of visits = 10,000 Supplies cost per visit = Cost of total supplies/Number of visits = 60,000/10,000 = $6 Total fixed costs = Wages and benefits + Rent + Depreciation + Utilities = 220,000 + 5,000 + 30,000 + 2,500 = $257,500 Cost structure = Total fixed costs + Supplies cost per visit x Number of visits = 257,500 + 6 x Number of visits b) Expected total costs for year 1 (10,000 visits) = 257,500 + 6 x Number of visits = 257,500 + 6 x 10,000 = $317,500 c) Total costs for 7,500 visits = 257,500 + 6 x Number of visits = 257,500 + 6 x 7,500 = 257,500 + 45,000 = $302,500 Total costs for 12,500 visits = 257,500 + 6 x Number of visits = 257,500 + 6 x 12,500 = 257,500 + 75,000 = $332,500 d) Average cost per visit at 7,500 vists = Total costs for 7,500 visits/7,500 = 302,500/7,500 = $24.2 Average cost per visit at 10,000 vists = Total costs for 10,000 visits/10,000 = 317,500/10,000 = $25.4 Average cost per visit at 12,500 vists = Total costs for 12,500 visits/12,500 = 332,500/12,500 = $26.6
