The current population of a town is 10,000. If the population, P, increases by 20% each year, which equation could be used to fi
frozen [14]

Answer:

<u>The equation would be:</u>

<u>p = 10,000 * (1 + 0.2)∧ t</u>

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Current population of a town = 10,000 inhabitants

Growth rate of the population = 20% annually

2. Which equation could be used to find the population after T years?

p = Population of the town after t years

t = Number of years

We will use the following equation:

<u>p = 10,000 * (1 + 0.2)∧ t</u>

For example, let's calculate the population after 6 years, replacing with the real values, we have:

p = 10,000 * (1 + 0.2)⁶

p = 10,000 * 2.986

p = 29,860 inhabitants
