Answer 1

The U.S. National Debt in 2015 was approximately 1.829 × 10¹³ dollars.

Step-by-step explanation:

To find the U.S. National Debt in 2015, we need to determine how much it increased by compared to 1915. According to the information provided, the debt in 2015 was approximately 5.9 × 10³ times more than in 1915.

To calculate the debt in 2015, we can multiply the debt in 1915 by this factor:

Debt in 2015 = Debt in 1915 * 5.9 × 10³

Substituting the value for the debt in 1915 (3.1 × 10⁹ dollars) into the equation above, we get:

Debt in 2015 = (3.1 × 10⁹ dollars) * 5.9 × 10³

Simplifying, we multiply the numbers:

Debt in 2015 = (3.1 * 5.9) × (10⁹ * 10³) dollars

Debt in 2015 = 18.29 × 10¹² dollars

Using scientific notation, the U.S. National Debt in 2015 was approximately 1.829 × 10¹³ dollars.
