Blouses are on sale for P 99.95. They are marked as being 27% off. What was the regular price?

Sagot :

We have:
[tex]99.95=(1-0.27)x=0.73x[/tex]
(Note that we need to do this since it is discounted)

[tex]99.95=0.73x \\ x= \frac{99.95}{0.73} =136.91[/tex]

The regular price was approximately 136.91 pesos.
To find the regular price:

100%-27%=73%
P 99.95 divided by 73%(simply 0.73)=P 136.92

Hope this helps =)
