Choose a number greater than 5,000 and less than 10,000 for the value of p.

Question

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

Answer 1

Let's suppose the chosen value of p is 7,500.

To calculate the estimated current population of Concord, we need to use the percentage change from part b. Let's say the percentage change is 10%.

To calculate the estimated population, we can use the formula:
Estimated population = Initial population + (Percentage change * Initial population)

Let's assume the initial population of Concord is X.
So, the estimated population of Concord would be:
Estimated population = X + (10% * X)

Since the percentage change is given as a decimal (0.10 in this case), we can rewrite the equation as:
Estimated population = X + (0.10 * X)

Simplifying further:
Estimated population = 1.10 * X

This means that the estimated population of Concord is 1.10 times the initial population.

Now, let's substitute the value of p (7,500) in our equation:
Estimated population = 1.10 * 7,500
Estimated population = 8,250

Therefore, the estimated current population of Concord is 8,250.
