The spirometer sums

Here is a small table of volumes from four people, in mL. You will write the sums for the capacities and find who has the largest vital capacity.

The idea. VC = TV + IRV + ERV, and TLC = VC + RV.

Your tasks.

1. Finish vital. It gives the vital capacity of a person from TV, IRV and ERV.
2. Finish total. It gives the total lung capacity from the same three numbers and RV.
3. Set best to the name of the person with the largest vital capacity.
