Answer:

the estimate would be 700, the actual answer is 706

Explanation:

when estimating, if it is 4 and or below then you have to round down. in this case since, 2 is below 4 (in the tens place) so we round to 620. and this also applies to the 84, since it is 4 and or below, we round to 80. 620 + 80 = 700
