Q

Thus if in total time she can make 40a, how long takes to make 1a?

And if some combination I’m herr time , what will this be

A

A/40

All the times for 1 x the amount must add to be less than equal to the total time, so 1
Less than bevause might be better for her not to use ALL HER TIME

A/40 + b/30 +x/10 <= 1!
