Answer

Estimate: $3,000; Exact:$3,001

Work Step by Step

To estimate, we first round the individual costs from 321 to 300, 51 to 100, 299 to 300, 1799 to 1800, 82 to 100, and 449 to 400. The estimated total cost is 300 + 100 + 300 + 1800 + 100 + 400 = 3,000. We find the exact total cost by adding the actual numbers: 321 + 51 + 299 + 1799 + 82 + 449 = 3,001.
