Project description
There are two variables that affect the cost of the service:
1. Availability/absence of a freight elevator;
2. Floor number.
It should work in this way: if it is noted that there is a freight elevator, then regardless of the floor number, the cost calculation will be equal to the price of lifting per floor; if there is no freight elevator, then the cost is equal to the multiplied values of the price for lifting 1 floor and the number of floors.
