Answer:
600,000
Step-by-step explanation:
When rounding to the nearest 100,000 if it's X50,000 you round up 1 for the X, if it's X49,999 or less you keep the X as is.
229,275 rounding to the hundred thousand would be 200,000
115,368 would be 100,000
344,633 would be 300,000
so 200,000+100,000+300,000 = 600,000
