A stereo at an electronics store originally costs $300, but it is on sale for 25% off. If a customer buying the stereo has a coupon for $40.00 off of any purchase, what will his final price be on the stereo?

OpenStudy (elkinsth):

is this spam also? NO

OpenStudy (mathmale):

No, this is a valid question.

OpenStudy (elkinsth):

well could someone help me?

If a customer buying the stereo has a coupon for $40.00 off of any purchase, what will his final price be on the stereo? If the stereo were originally priced at $300, but is on sale at 25% off, multiply $300 by 75%. Mind doing that now?

OpenStudy (elkinsth):

225?

OpenStudy (mathmale):

Yes. Now, there's some ambiguity here. Do we want 40% off the original price, or do we want 40% off the sale price? Why not calculate both? Mult $225 by (1.00-0.40). Then mult. $300 by the same.

OpenStudy (elkinsth):

125 and 140

OpenStudy (mathmale):

We don't know which was meant by the original question. Did you remember to subtract 0.40 from 1.00? Your 125 and 140 look too small.

OpenStudy (mathmale):

"40% off the original retail price" would come to what amount?
