What is the total amount in GBP(£)?
This would be the sum of (1) + (6), or in your case, 1,442.40 + 2,500.
which is very confusing for me, and I am unsure of how to answer it.
The forms can seem vague because they have to cover a lot of different situations. But the questions have been reviewed and nitpicked back-and-forth both internally in UKVI and externally by members of the UK legal community. They are reviewed twice annually and the one you are currently filling out is in an advanced 'beta' stage.
They are not going to refuse if you interpret the questions differently and compute the sum from some of the other questions. They are not that captious. The main thing they will be looking for is if the cost of the visit map back to the stated premise and the capacities of the applicant and sponsor(s). They also worry a lot about provenance so be sure your sponsor's funds are adequately sourced.
