Answer:
$19575
$20945.25
Step-by-step explanation:
The current price of the car is $43500 but if I wait for 18 months, then it will be 55% cheaper.
So, the after 18 months the price of the car will be [tex]43500(1 - \frac{55}{100}) = 19575[/tex] dollars.
If sales tax is 7%, then the total price of the car after waiting for 18 months will be [tex]19575(1 + \frac{7}{100}) = 20945.25[/tex] dollars. (Answer)
