@timid furnace what is your unknowns?

For example let x,y the number of mountain bike and road bike respectively

First you need to express what the problem says to equations and inequalities

"they must produce at least 250" means x+y≥250

Now whats the equations of the profit?

And what is the inequality that expresses the time constraint?

They need to produce them in 31*40=1240 hours or less right?
