The sale price of the TV = $600.
It is said the sale price is after a 20% less than the rgular price.
So the if the regular price P , then after 20% reduction, the sale price is P - P(20/100) = P- P/5 = 4P/5.
Therefore 4P/5 should be equal to $600 sale price.
So 4P/5 = $600.
Multiplying both sides of the equation by 5 , we get:
(4P/5)*5 = $600*5.
4P = $3000.
Divide both sides by 4:
4P/4 = $3000/4
P = $750.
Therefore the regular price of the TV = $750.
