Answer

Estimate: $1300; Exact: $1254

Work Step by Step

To estimate, we first round the individual costs from 299 to 300, 185 to 200, 99 to 100, 67 to 100, 395 to 400, and 209 to 200. The estimated total cost is 300 + 200 + 100 + 100 + 400 + 200 = 1300. We find the exact total cost by adding the actual numbers: 299 + 185 + 99 + 67 + 395 + 209 = 1254.
