Answer:
See below.
Explanation:
Lets summarize the information first,
Revenue = 480/hour
Salaries = 11700 + 126/ hour
Supplies = 5/hour
Equipment Rental = 2000 + 22/ hour
Insurance = 3900
Miscellaneous = 520 + 1.48/hour
Now we flex these standard costs to to activity level of 290 diving hours,
Revenue (480 * 290) 139,200
Less:
Salaries and wages (11,700 + 126*290) 48,240
Supplies (5 * 290) 1,450
Equipment rental (2000 + 22*290) 8,380
Insurance 3,900
Miscellaneous (520+ 1.48*290) 949.2
Budgeted profits $76,280.8
Hope that helps.
