The net price of a calculator is $54 after a 10% discount is applied.

What is the list price?

It seems that I should start out with this: (where x = list_price)

x - ( x(.10) ) = 54

...but I can't figure out where to go from there.

I know I can instead start out with this:

x(.90) = 54 check: 60 - ( 60(.10) ) = 54

/.90 /.90 60 - 6 = 54

x = 60

check: 60(.90) = 54

But that seems like a jump and that I should be trying to work from the first one to the second. What should I do?

(this is out of an old book , I have no instructor.)

Thank you.
