To get the union of two sets of numbers, all you do is combine the numbers from least to greatest. If a number repeats in the 2 sets, you only put it once.
 
        
                    
             
        
        
        
The answer is $41.12
(Work is below)
First add the total of the vase and shipping-
Vase:                    $34.99
Shipping:              $   3.00
                         +__________
                             $37.99
Then calculate sales tax by multiplying $37.99 x 0.0825 -
Above Total:         $37.99
Sales Tax Rate:    $   0.0825
                         x__________
                              $  3.1341
You round down because ^ less than five (five or above you would round up)
Sales Tax:             $3.13
Then you add the sales tax to the above total
Vase:                    $37.99
Shipping:              $  3.13
                         +__________
                             $41.12
