Answer:
$160 was the price at which glasses were advertised.
Step-by-step explanation:
Nick bought a pair of glasses for 200.
He later saw the same glasses advertised for 20% less than what he originally paid.
We have to find the price of the glasses as per advertisement.
Price of the sunglasses after discount of 20% = Price Nick paid - 20% of price Nick paid
= 200 - 20% of 200
= 200 - 200×[tex]\frac{20}{100}[/tex]
= 200 - 200×0.2
= 200 - 40
= 160
Therefore, the price of the glasses was $160 in the advertisement.
