Answer

Estimate: 30; Exact: 32

Work Step by Step

To estimate the number of homes that can be fenced, we first round 180 to 200 and 5760 to 6000, then divide the rounded total amount of fencing material by the amount per home: 6000 / 200 = 30 To find the exact number of homes that can be fenced, we divide the actual total amount of fencing material by the amount per home: 5760 / 180 = 32
