12

Step-by-step explanation:

The expression that represents the town's population after 5 years.

Step-by-step explanation:

Given:

Current population of Springfield, USA = 9,900

Rate of growth per year = 2.3%

To find the expression that represents the town's population after 5 years.

Solution:

The exponential growth expression is given as:

where :

represents the final population after years

represents the initial population

represents the rate of growth in percent

Plugging in  the known values.

Simplifying.

Thus, the above expression represents the population after 5 years.

Ibelieve the answer should be 11493 people 7 years from "now".

It usually asks what the population will be in years. Anyways, 9900=(1+0.023)^ [however many years]. I’ve done this problem before, and I believe it was 7 years, so you will “raise it” to 7 or whatever the number is.

The expression would be:  9900(1.023)^7

This is an example of an exponential equation. They are in the form y = ab^x. A is the starting value and b is the rate of change.

The rate is 1.023 because we are adding on 2.3% each time.
