Calculate the total cost of an item bought at a negotiated price of $17,250 with 7.7 percent sales tax and a $115 registration fee. (points : 10)
$17,270
$17,396.75
$18,693.25
$18,598.25

Well this means we would have to find the sales tax but all we have to do is add the registration fee to the total.
But in order to solve this we need to know 7.7% as a decimal.
7.7% = 0.077 
now we multiply that by our 17,250 in order to get our tax
sooo lets do the math:)
$17,250 x 0.077 = 1,328.25
So we add that to our 17,250 since we need to add the tax
s
$17,250 + $1,328.25 = $18,578.25
but wait! theres more... remember we had to add the registration fee? 
lets do that:)
$18,578.25 + $115 = $18,693.25
so clearly our answer i
C.) $18,693.25
i hope this helps:)
