All we need to do is subtract each number by 344 and see which number is the lowest
344 - 320 = 24
360 - 344 = 16
Therefore, 360 is closest to 344
Hope this helps

Alright well for (A) you will round $5280 to $5300. Then you multiply $5300 by 28.
For (B) you just round up. So again $5280 rounds up to $5300.
