siniylev [52]

Answer:

17852.5$

Step-by-step explanation:

I already answer this in another part, but here it is againa:

In this case, all you need to do is sum all the amounts and take out the down payment of 2500$

First, the car of 18,500 with the 6.5% sale tax, it would be:

18,500 * (6.5/100) = 1202.5$

18500 + 1202.5 = 19702.5$

Now the charge and fees:

450+155+45 = 650$

Then:

19702.5 + 650 = 20352.5$

Finally, the down payment:

20352.5 - 2500 = 17852.5 $
