A TV is regular priced at $1,200. However, the store has the TV on sale at 10% off. How much would the TV cost at the sale price?

10% of $1,200 is $120 and after the discount the TV would cost $1,080.


I believe you are asking what is the 10% discount on a $1,200 TV or what is 10% of $1,200.

"Percent" or "%" means "out of 100" or "per 100", Therefore 10% can be written as #10/100#.

When dealing with percents the word "of" means "times" or "to multiply".

Finally, lets call the number we are looking for "n".

Putting this altogether we can write this equation and solve for #n# while keeping the equation balanced:

#n = 10/100 xx 1200#

#n = 12000/100#

#n = 120#

If what you are asking is how much is the TV after a 10% discount then you would subtract the $120 from the $1,200 to get:

#1200 - 120 = 1080#
