Answer
Estimate: 10,000,000; Exact: 12,073,571
Work Step by Step
To estimate, we round 37,341,989 to 40,000,000 and round 25,268,418 to 30,000,000. We find the estimated difference by subtracting the rounded population of Texas from the rounded population of California:
40,000,000 - 30,000,000 = 10,000,000
To find the exact difference, we subtract the actual population of Texas from the actual population of California:
37,341,989 - 25,268,418 = 12,073,571
