Would really appreciate some guidance on this question. Admittedly I'm not very good at it or just don't understand what I'm doing.
In a quality control process to check a batch of parts the number of acceptable parts is (x), the number of rejected parts is (y) and the % of acceptable parts for the whole batch is (k)
a)Setup an equation for (k)
b) if 60% of rejected parts can be fixed has to be scrapped which is (z), setup an equation for (z)
If 60% of rejected parts can be fixed and z is the number of rejected which must be scrapped. Setup an equation for z ............[edited]
c) determine (z) if (x)=850 and (k)=85%
So for a) I've come to.. x(x+y/100)
For b) I've come to (40y/100)=z
For c) I'm abit lost. As the numbers are too extreme so I must have done the first stages wrong.
Thanks for any pointers.
