Question 316317
The question tells you that there is a 30% reduction.

This means we are dealing with 100% - 30% = 70%.

Then the question becomes 70% of what is $460?

Changing 70% to decimal number 0.70, the word "what" to any letter that you like (I will use x) and the word "is" to the equal (=) 
sign, our equation becomes 0.70x = 460

We are looking for x which is the original price of tv.

Can you find x now?
