So I have this question in my texbook and I'm completely lost using solver in Excel. The actual question itself seems pretty straightforward, but I have no idea how to use solver to maximixe production. Apologies if this is not the correct subject. Wasn't sure if this would be Accounting, Econ or just Algebra. I appreciate any help on this.

United Manufacturing is planning on spending up to $4,000,000 on new automated assembly machinery. They have decided to purchase two different models of equipment and are trying to decide how many of each model they should purchase. The F300 model costs $350,000 each. The S250 model costs $220,000 each. The F300 has some extra features so at least one third of the models purchased should be the F300. The annual maintenance budget for the new equipment is set at $120,000. The annual maintenance cost of each F300 is $12,000. The annual maintenance cost of each S250 is $7,500. Each F300 will produce 125 units per day. Each S250 will produce 81 units per day. Set up a worksheet and then use Solver to determine how many of each model to purchase so that the daily production is maximized as long as the other constraints are met
