Answer:

The percent increase of the population of chipmunks was 29%

Step-by-step explanation:

we know that

The population of 300,000 chipmunks represent the 100%

The increase of population is equal to

(387,000-300,000)=87,000 chipmunks

Using proportion find the percent increase

Let

x-----> the percent increase

300,000/100%=87,000/x

x=100*87,000/300,000

x=29%

<h3>What is Unitary Method?</h3>

The unitary method is a method in which you find the value of a unit and then the value of a required number of units.

For example: 5 cars have price of $500. what will be the price of 10 cars.

Now, we know

5 cars → $500

1 car → $500/5

1 car → $100

10 cars → 8 x $100

10 cars → $800

The standard drink contains 12 - ounce of beer.

Here, we have given 1 red cup which has 16 - ounce of beer.

He has 3 red cups.

So, total ounce of beer he has consumed in two hour time period:

16 x 3 = 48 ounce of beer.

Now, as we know standard drink contains 12 - ounce of beer.

so, Number of standard drink = 48/12 = 4

Hence, 4 Standard drinks he has consumed in over a two - hour time period.
