Ms.Stacey buys a new truck for $42,000 the salesperson makes a 3% commission what was the salespersons commission on the sale?

Total number of trees in the park = 75
Number of trees that are at least 30 feet tall = 6
Then
Number of tress that are less than 30 feet tall = 75 - 6
                                                                          = 69
So
Percentage of trees that are less than 30 feet tall = (69/75) * 100
                                                                                = (69 * 4)/3
                                                                                 = 276/3
                                                                                 = 92 percent
So the percentage of trees that are below 30 feet is 92%. I hope the procedure is clear enough for you to understand.
