I just solved a question similar to this
Let's understand it
It's saying she got 660 or it is that her weekly pay is 660
So now let weekly pay which is P be 660
Hence the formulae is given
It's 480 + 18 (h – 30) = 660
Now its just boring calculation
If you mark it brainleist I will do the calculation for you wink wink
Never mind
480 + 18 (h – 30) = 660
18 (h – 30) = 660-480
18 (h – 30) = 120
(h – 30) = 120/18
(h – 30) = 6.6
h = 6.6+30
h= 36.6
So dam the Judy lady worked for 36.6 hours
