Question

Add a fourth row to the table showing the population information for the town of Concord. Concord’s population as of the last census was p people;  for its percentage change, choose a negative integer not divisible by two. Write two expressions showing the current estimated population of Concord in terms of p.

Answer 1

To add a fourth row for the town of Concord, let’s assume Concord's population is represented by \( p \) and its percentage change is -3% (a negative integer not divisible by two).

Here's how we can lay out the table:

| Town | Population (p) | Percentage Change (%) | Current Estimated Population | |------------|----------------|-----------------------|------------------------------| | Town A | 1000 | 5 | 1050 | | Town B | 2000 | -10 | 1800 | | Town C | 1500 | 0 | 1500 | | Concord | \( p \) | -3 | \( p \times (1 - 0.03) \) or \( p \times 0.97 \) |

Now, the two expressions showing the current estimated population of Concord in terms of \( p \) are:

1. \( p \times (1 - 0.03) \)
2. \( p \times 0.97 \)

Both of these expressions represent the estimated current population after applying the -3% change.
