Answer 1

Given:

The population of a town increases by 9 % annually.

The current population is 4,500.

Required:

We need to find the equation that gives the population of the town.

Step-by-step explanation:

The population can be found by the following equation.

`Th\text{e population =4500+9 \% of 4500}`

Let now be the current population of the town =4500.

Let Next be the population of the town.

The population can be found by the following equation.

`Next\text{ =Now+9\% of Now.}`

`Next\text{ =Now+}(9)/(100)*\text{Now.}`

Take the common term now out.

`Next\text{ =Now\lparen1+}(9)/(100))`
`Use\text{ }(9)/(100)=0.09.`

`Next\text{ =Now\lparen1+0.09})`

`Next\text{ =Now\lparen1.09})`

`Next\text{ =Now}*\text{1.09}`

Final answer:

`Next\text{ =Now}*\text{1.09}`
