A concert promoter sells tickets and has a marginal-prot function given below, where P'(x) is in dollars per ticket. This means that the rate of change of total prot with respect to the number of tickets sold, x, is P'(x). Find the total prot from the sale of the rst 130 tickets, disregarding any xed costs. P'(x) = 4x 1089 c:) The total prot is 99D. (Round to the nearest cent as needed.)
