Respuesta :

The answer is $143.70
(Work is below)

First calculate sales tax by multiplying $124.95 x 0.07 -
Model Rocket Kit: $124.95
Sales Tax Rate:    $    0.07
                         x__________
                              $  8.7465
You round up because      ^ more than five (four or below you would round down)

Sales Tax:             $8.75

Then you add the sales tax to the model rocket and add the shipping.

Model Rocket Kit:  $124.95
Sales Tax:              $    8.75
Shipping                 $  10.00

                         +__________
                               $143.70
