A new water park had 797 visitors on its first day. The park's manager expects to have that many visitors each day for the whole first week. He worked out that the park would have 7,829 visitors during the first 7 days. Does that sound about right?

No — that’s too high.

Estimate: round 797 to 800. Then 800 × 7 = 5,600, so about 5,600 visitors is reasonable.

Exact: 797 × 7 = 5,579. The manager’s 7,829 is 2,250 more than the correct total.
