The total of the combined salaries of all the employees at Company E after July 1 last year was 110% of that before July 1 last year.

Explanation:

If we use numbers, as example, we can get that:

Before July 1st Company E' s employes had in average salary of $100.000 (example).

If, after the decreased of employees, average salary was 10% percent more, that means that:

$100.000 x 10% = $10.000

So, total of combined salaries after decreased was

$100.000+$10.000 = $110.000

$110.000 is the 110% of the average salary before decreased because:

$110.000/100.000 = 110%
