This table shows the dollar amount customers have in their bank account. which expression would give the best estimate of the total amount in the accounts?

200+400+500+800
200+500+600+800
300+500+500+800
300+500+600+900

i think the second one would be the best estimate.

the rule for rounding is 5+ you would go up and 4 below you would round down, so:

221 -> 200

485 -> 500

562 -> 600

833 -> 800

therefore, 200+500+600+800 is the answer

b is the correct answer
