Hello, please help solving this step by step calculations. I appreciate your knowledge.

Garner Strategy Institute (GSI) presents executivelevel training seminars nationally. Eastern University (EU) has approached GSI to present 40 oneweek seminars during 2022. This activity level represents the maximum number of seminars that GSI is capable of presenting annually. GSI staff would present the weeklong seminars in various cities throughout the United States and Canada. Terry Garner, GSl's president, is evaluating three financial options for the revenues from Eastern: accept a flat fee for each seminar, receive a percentage of Eastern's profit before tax from the seminars, and form a joint venture to share costs and profits. Estimated costs for the 2022 seminar schedule follow: Garner Strategy Eastern Institute University Fixed costs for the year: Salaries and benefits $ 184,909 N/A* Facilities 64,900 N/A* Travel and hotel 9 $ 218,900 Other 78, 999 \"/39! Total fixed costs $ 318,909 $ 218,900 Variable cost per participant: Supplies and materials 9 $ 4? Marketing a 18 Other site costs 9 35 *Eastern's fixed costs are excluded because the amounts are not considered relevant for this decision (i.e., they will be incurred whether or not the seminars are presented). Eastern does not include these costs when calculating the profit before tax forthe seminars. EU plans to charge $1,200 per participant for each oneweek seminar. It will pay all variable marketing, site costs, and materials costs. Required 1. Assume that the seminars are handled as a joint venture by GSI and EU to pool costs and revenues. a. Determine the total number of seminar participants needed to break even on the total costs for thisjoint venture. b. Assume that thejoint venture has an effective income tax rate of 30%. How many seminar participants must thejoint venture enroll to earn an aftertax income of $289,926? 2. Assume that GSI and EU do not form a joint venture, but that GSI is an independent contractor for EU. EU offers two payment options to GSI: a flat fee of $9,500 for each seminar or a fee of 40% of EU's prot before taxes from the seminars. Compute the minimum number of participants needed for GSI to prefer the 40% fee option over the flat fee
