the first one because you multiply .2 by the regular price

Well, you would multiply 0.2 x the value of the jeans, then subtract the value of the jeans by that, so what is your answer?

@countryboy212 Please don't listen to @Mehek14 . He is incorrect.

anonymous · Answer

f(x) = x - 0.2x

For example, let x=10
f(x)=10-0.2(10)
f(x)=10-2
The sale price will be $8.
