Show worked solution
Add every value in the named row or column — include all periods, and don't average. The correct answer is 1,200. Traps to avoid: 750 comes from the "partial sum" error; 870 comes from the "partial sum" error; 400 comes from the "mean not total" error; 1,650 comes from the "double count" error.
