Calculate the total cost of an item bought at a negotiated price of $15,640 and a $2,500 trade-in allowance. the sales tax is 7.2 percent sales tax with an $86 registration fee. $13,140 $14,352.08 $1,212.08 $14,266.08

B.  $14352.08

Step-by-step explanation:

Let us find cost of item after 7.2% of sales tax. The cost of item after 7.2% of sales tax will be equal to 15640 plus 7.2% of 15640.

Therefore the cost of item after 7.2% of sales tax will be $16766.08.

Now let us add registration fee to the cost of item.

Now let us subtract $2500 trade allowance to find the total cost of the item.

Therefore, the total cost of item will be $14352.08 and option B is the correct choice.
