37.5 is a 20% markup from which number? Explain how you found that number?

31.25

Step-by-step explanation:

Okie dokie, so if something is marked up by 20% it means, it is 120% the original number right?

So we can convert 120% into 1.2 to make solving this problem easier. :)

So if we want to find the original number, all we have to do is divide 37.5 by 1.2.

This gets us 31.25.

the correct answer is 5 6 and 7

5+2x=a
