(1) His new salary will be 10% higher than his old salary.
No info on state tax. If it's 5%, then 50000 + 10% *1.1 - 5% *0.95 = 52250
if it's 10%, then 50000 + 10% *1.1 - 10% *0.9 = 49500.
Not sufficient.
(2) New taxes = $2200 .
No info on his new salary. Not sufficient.
(1) & (2) Together
We have both, his new salary and the amount of state tax for the year, notice that unlike in question stem, we got this amount in absolute value and not in percentage of total income.
