420 is correct. 
You round

17 to 20
73 to 70
289 to 300
27 to 30

20+70+300+30=420.

When you round 289 to the greatest place, you round it up to 300. 
Underline the 2.  Go next door to the 8.  Since 8 is more than 5, 2
becomes 3 (it goes up by 1) and everything to the right becomes a
zero.  Hope that helps.
