John tucker is interested in purchasing stock. he wants to determine the costs.

a0 =$97.5  ; a1 =$87.96 ; a2=$282.48; a3=$1,722.5 ; a4=$1,553.96 ; a5=$4,990.48

Step-by-step explanation:

Hi, to solve this problem we have to multiply each total by the commission in decimal form (6 / 100= 0.06).

So:

$1625 x 0.06 = $97.5

$1,466 x 0.06 =$87.96

$4,708 x 0.06 =$282.48

And finally, to obtain the total costs we have to add to each total the commission of the total.

$1625 + $97.5 = $1,722.5

$1,466 +$87.96 = $1,553.96

$4,708 +$282.48 = $4,990.48

Feel free to ask for more if it´s necessary or if you did not understand something.

                    commission @6%                                Total Cost

$1,625 x 0.06 = $97.5                             $1,625 + $97.5 = $1,722.50
$1,466 x 0.06 = $87.96                          $1,466 + $87.96 = $1,553.96
$4,708 x 0.06 = $282.48                         $4,708 + $282.48 = $4,990.48

We have such equation
       /:6.2        (multiply both sides by 6.2)
x= - its the answer
