Question: 

Mr. Latif has two factories for producing two different electronic devices and he wants to calculate the total profit of two factories in the end of the year. Where each factory has different profit per year.

• First Factory produced Q₁ PC’s during the year. The price per each unit of PC is $P₁, while the variable cost per each unit is $v₁, and Fixed Costs are $FC₁;
• Second Factory produced Q₂ Monitor’s during the year. The price per each unit of Monitor is $P₂, while the variable cost per each unit is  $v₂, and Fixed Costs are $FC₂;

A profit for a company (one factory) is calculating using this formula:

Profit   = Total Revenue – Total Costs

            = Total Revenue – (Variable Cost +Fixed Costs)

Profit   = P*Q – (v*Q + FC)

Where:

• P: is price per each unit,
• Q: is quantity (number of products)
• v: is variable cost per each unit
• FC: is Fixed Costs

What is the total profit of the two factories?

Input Specifications: You will be given four inputs P, Q, v, FC for each factory. Where 50.00<=P<=300.00, 100<=Q<=50000, 20.00<=v<=1500.00, 3000.00=< FC<= 50000.00 

Output Specifications: Show the total profit of the two factories
