Re-word this in 7th grade writing.
1. Expression using the population at the last census (x):
Current Population = x + (y/100) * x
= x * (1 + y/100)
2. Expression using the current estimated population (z):
Current Population = z + (y/100) * z
= z * (1 + y/100)
In these expressions, x, y, and z represent the relevant values from the table.
b. Let's assume that the census population of Town A is 6,742 people. Based on the percentage change for that town, we can calculate the estimated current population using the expression derived in part (a).
If the census population is 6,742 people, and the estimated increase or decrease in population is given as a percentage, we need to substitute these values into the expression.
Let's say the estimated increase or decrease in population (y) is -2%. We can use the expression:
Current Population = x * (1 + y/100)
Current Population = 6,742 * (1 - 2/100)
Calculating the expression:
Current Population = 6,742 * (1 - 0.02)
Current Population = 6,742 * 0.98
Current Population ≈ 6,603.16
Rounding to the nearest whole number, the estimated current population of Town A would be approximately 6,603 people.
