Please help! I am stuck on this practice question!

Alyeski Tours operates day tours of coastal glaciers in Alaska on its tour boat the Blue Glacier. Management has identified two cost drivers-the number of cruises and the number of passengers-that it uses in its budgeting and performance reports. The company publishes a schedule of day cruises that it may supplement with special sallings if there is sufficient demand. Up to 84 passengers can be accommodated on the tour boat. Data concerning the company's cost formulas appear below: For example, vessel operating costs should be $6.400 per month plus $474.00 per crulse plus $3.50 per passenger. The company's sales should average $33.00 per passenger. In July, the company provided 54 cruises for a total of 3.050 passengers. Required: Prepare the company's flexible budget for July
