A sign in a clothing store said, "All prices reduced 25% . Final prices marked on tags." DeLea found a sweatshirt that showed a price of $27. What was the original price of the sweatshirt? A. $27.25 B. $33.75 C. $36.00 D. $52.00
To be sure, is this 2.5 percent, or 25?
its 25%
Okay so I just reread what I saw from iluvlucy and I was wrong, you need to multiply the two numbers, and then try and figure it out from there.
ok
Now remember, normally you would have divided the numbers to get the second part of your answer, but since it's a decimal you have to multiply. So the multiplication only attends to the decimals and I'm pretty sure on fractions, anyone want to help me out on the fractions? I hate giving out wrong information.
\[$-$\%=cost\] \[$(1-\%)=cost\] \[$=\frac{cost}{1-\%}\]
Rewriting your equation here amistre maybe this is more simply put: \[% * discount cost = % taken off original then simply + your % taken off \to the discount price.\]
i got 6.75
That is correct ebso, that is the discount in $ form, now what should you do to get your original price from discount?
Lol, Uh divide 6.75 & 25% ????
No, instead think of it this way: x = 6.75 z = original cost 27 + x = z now what does z equal?
33.75?
Good job, that's correct!
Kk, Thanks ! :)
