Which equation can be used to represent this information?

r=s+5

Step-by-step explanation:

So, letsgo over what we know:

The regular price is r

The sale price is s

Now lets compare the difference between r and s:

10r = 5s

20r = 15s

30r = 25s

What is the difference between the r and s value in each situration?

Well, from what I can see, r is always 5 more than s.

This can be writen as:

r = s+5\

So this is our equation, for if you plug in any number for s, you will get an accurate r value.

For instance, if you say s is 25:

r=25+5

=

r=30

This looks just like the 30r=25s in the table above.

So:

r=s+5

Hope this helps! :)

that would be 2 1/2 * 12

= 24 + 6
