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.
| Town | County | State | Population |
|---------|------------|---------|------------|
| Concord | Middlesex | MA | p |
what
Apologies for the confusion. Here is the updated table:
| Town | County | State | Population |
|---------|------------|---------|------------|
| Concord | Middlesex | MA | p |
To express the current estimated population of Concord in terms of p, we can use two expressions:
1. the population decreased by 10%:
Estimated population of Concord = p - 0.1p = 0.9p
2. the population decreased by 20%:
Estimated population of Concord = p - 0.2p = 0.8p
thx
You're welcome! If you have any more questions, feel free to ask.

Choose a number greater than 5,000 and less than 10,000 for the value of p.
Based on the percentage change you chose in part b, calculate the estimated
current population of Concord, rounding to the nearest whole number if
needed. Explain why you used the expression you did to make your calculation.
Let's choose a value for p that is greater than 5,000 and less than 10,000. For example, let's set p = 8,000.
Since you mentioned in part b to choose a negative integer not divisible by two as the percentage change, let's choose -7 as the percentage change.
Using the first expression to calculate the estimated current population of Concord, with a percentage change of -7, we have:
Estimated population of Concord = p - 0.1p = 0.9p
Plugging in the value of p = 8,000, we have:
Estimated population of Concord = 0.9 * 8,000 = 7,200
Rounding this number to the nearest whole number, the estimated current population of Concord is 7,200.
We used the expression 0.9p because we subtracted 10% from the original population. Using the value 0.9 gives us the new population after a 10% decrease.
