Answer 2

Answer:

The American consumed $3.205\times 10^8$ gallons of gasoline.

Step-by-step explanation:

We are given the following information in the question:

Gasoline consumed by the Americans = 320,500,000 gallons

We have to convert this number into scientific notation.

• Scientific notation is a method  of writing very large or very small numbers.
• A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10.

The above number can be written in scientific notation in the following manner:

$320,500,000 = 3.205\times 10^8$

Hence, the American consumed $3.205\times 10^8$ gallons of gasoline.
