The annual Gross Domestic Product (GDP) of a country is the value of all of the goods and services produced in the country during a year. During the period 1985-1999, the Gross Domestic Product of the United States grew about 3.2% per year, measured in 1996 dollars. In 1985, the GDP was $577 billion.

In what year will the GDP reach $2 trillion? You just need to give the year, not part of a year.

To determine the year when the GDP will reach $2 trillion, we can use the compound interest formula. The formula for compound interest is:

A = P(1 + r)^n

Where:
A = Future value (in this case, $2 trillion)
P = Present value (in this case, $577 billion)
r = Annual growth rate (3.2% per year)
n = Number of years

Let's plug in the values and solve for n:

$2 trillion = $577 billion * (1 + 0.032)^n

Dividing both sides of the equation by $577 billion:

3.46 = (1 + 0.032)^n

Now, let's take the logarithm (base 10) of both sides:

log(3.46) = n * log(1.032)

Using a calculator, we calculate that log(3.46) ≈ 0.538 and log(1.032) ≈ 0.012.

Now, let's divide both sides of the equation by log(1.032):

0.538 / 0.012 ≈ n

n ≈ 44.8

Since we can't have a fraction of a year, we round up to the next whole number. Therefore, n ≈ 45.

To determine the year, we add 45 years to the initial year of 1985:

1985 + 45 = 2030

Therefore, the GDP will reach $2 trillion in the year 2030.

To find the year when the GDP reaches $2 trillion, we can use the information given about the growth rate of the GDP.

Let's calculate the growth rate per year from 1985 to 1996:
Growth rate per year = 3.2% = 0.032

To find the GDP for a specific year, we can use the formula:
GDP = Initial GDP * (1 + Growth rate)^Number of years

Let's calculate the number of years required to reach $2 trillion:
$2 trillion = $577 billion * (1 + 0.032)^Number of years

Dividing both sides of the equation by $577 billion, we get:
(1 + 0.032)^Number of years = $2 trillion / $577 billion

Taking the logarithm of both sides to solve for the number of years:
Number of years = log($2 trillion / $577 billion) / log(1 + 0.032)

Calculating this using a calculator, the number of years is approximately 15.42 years.

Therefore, the GDP will reach $2 trillion in approximately 15 years and 5 months from 1985.

Adding this to the initial year of 1985, the GDP will reach $2 trillion in approximately the year 2000.
