Account for costs

To calculate our profits, we first need to take into account our costs.

Add the following value nodes to our simulation:

Cost per glass:

• Label → Cost per glass
• Tag → cost_per_glass
• Value Input → 1

Fixed daily costs:

• Label → Fixed daily costs
• Tag → fixed_daily_costs
• Value Input → 20

Total daily costs:

• Label → Total daily costs
• Tag → total_daily_costs
• Value Input → =#fixed_daily_costs + #cost_per_glass * #glasses_sold_per_day
