Today only, a suit is being sold at a 29% discount. The sale price is $639. What was the price yesterday?

Question

This is a college algebra word problem/question that I need assistance with. Thank you

Answer 1

Hi again Tati.

We can solve this by thinking of the full price as 100% (x)

So we take $639, which is 71% of the price.

71% of 100% (x) = $639

.71x = $639

All we need to do now is simplify this algebra equation

639/.71 = $900

Very useful to do this at the mall!

Let's meet up! I can help you with more problems like this in person. Talk with you soon, Tati.  Just shoot me a message, i'm near you.

Answer 2

If the discount is 29%, this means you pay only 71% of the original price.

71% of what number equals $639 ?

71%*n=$639

0.71*n=639

n=639/0.71

n=$900

check: 71%*$900=0.71*900=$639
