Question

During the year 2013 approximately 7.07 x10 to the power of 9 pennies were minted (made by the U.S. Mint). In the year
2000 approximately 1.43x 10 to the power of 10 were minted. Estimate how many times more pennies were minted in the
year 2000 compared to the year 2013. Give a possible explanation for the decline.

Answer 1

Using proportions, it is found that 2.04 times more pennies were minted in the year 2000 compared to the year 2013.

What is a proportion?

A proportion is a fraction of a total amount. From it, the amount of times a measure a is greater than a measure b is given by a divided by b.

In this problem:

• In 2013, the quantity was of $7.07 \times 10^9$.

• In 2000, the quantity was of $1.43 \times 10^{10}$

Hence, 2.04 times more pennies were minted in the year 2000 compared to the year 2013.

Hence, applying the proportion:

$\frac{1.43 \times 10^{10}}{7.07 \times 10^9} = \frac{14.3 \times 10^9}{7.07 \times 10^9} = 2.04$
