This is just like last time but here we are subtracting and not adding..which means instead of adding interest, there is a discount.

OpenStudy (anonymous):

Ok

OpenStudy (igreen):

For example, we can rule out Option B, because it mentions adding tax, but we are SUBTRACTING(discount), and not ADDING(interest/tax), therefore B is incorrect.

OpenStudy (anonymous):

Okay so

OpenStudy (anonymous):

D has a discount in it

OpenStudy (igreen):

Yep, you got it..

OpenStudy (anonymous):

So its D?

OpenStudy (igreen):

Taking 22% discount from the original.. s - s(22%)

OpenStudy (igreen):

That is how we calculate discounts..yes, it's D.
