Question 1026978: I am trying to understand this math problem:
The after tax price of a used care is $12,990.60. If a 4% sales tax was charged, what was the pre tax price of the car?
So far I got:
12,990.60(0.04)=51,962.40
51,962.40-12,990.60=3,897.180
I am kind of confused...

Such practical problems need some thinking,
If car after tax price was 104 then price is 100
12,990.60 was paid
12990.60/104 * 100
=12490.96 is the pre tax price
