Answer:

225

Step-by-step explanation:

The rounding system is used by rounding the numbers so by rounding the method would be:

[tex]222=200 after-rounding\\203=200 after rounding\\rounding sum=220[/tex]

And compatible numbers would be rounding to the nearest five:

[tex]222=220 after-rounding\\203=205 after rounding\\rounding sum=225[/tex]

So the compatible numbers gives you the exact answer but it´s not always this way.
