Answer:
$2399.99
Explanation:
the price of the tv is discounted by 25% 
that is the same as saying the tv is 75% of its original price 
so we take $1799.99/75 to see what one percent of the price is 
$1799.99/75=23.9998
then we take 23.9998*100 to see what the original price was 
23.9998*100=2399.986667 and then we round to the nearest hundredth 
so 2399.99
