I got the same answer as Mark, but I think I went about it a different way. I didn't find it difficult to come up with an equation to describe the situation, but I really struggled to then solve that equation for x because I'm so rusty! In the end, I had to plug numbers into my equation as I just couldn't solve it any other way! I suspect I may have made it more difficult for myself than I needed to.
Here's my working, if anyone is interested/wants to point out where I went wrong:
We were looking for number of days worked, so I called that x
Pay for days worked = 9x
Days not worked = 30 - x
Pay deducted = 6(30 - x)
So 9x - 6(30 - x) = 0
Solve for x
9x = 6(30 - x) - I added 6(30 - x) to both sides
9x/(30-x) = 6 - I divided both sides by 30-x
Then I tied myself in knots and couldn't remember how to get any further!
I knew x had to be a number between 1 - 30, so I then plugged numbers in and used how close they were to giving me 6 in that equation to work out how far off I was.
