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.)
