Answer:
$2399.99
Step-by-step 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
