Question

Growing up, Joe lived in a small town. When he left for college, the population was 840. The population has grown by 5% after Joe's first year of college. What is the new population?

Answer 1

First, I'll find the actual amount of the increase. Since the increase is five percent of the original, then the increase is:

(0.05)(840) = 42

The new population is the old population plus the increase, or:

840 + 42 = 882

The population is now 882.

Answer 2

Answer:

Growing up, Joe lived in a small town. When he left for college, the population was 840. The population has grown by 5% after Joe's first year of college. The new population is 882.

Step-by-step explanation:

It is given in the question that,

Growing up, Joe lived in a small town. When he left for college, the population was 840.

Again,

The population has grown by 5% after Joe's first year of college.

Now, The new population will be the sum of old population with the number of population increases.

Population increases,

840×5%=42

Hence, the new population will be,

Old population + number of population increases

840+42=882

Again in another way we can simplify,

Increase the population by 5% after Joe's first year of college i.e., the mathematical expression of the given conditions is as follows,

840×(5%+1)

Simplify the mathematical expression,

840×1.05

Determine the quotient or product,

882

The new population is 882.
