Explanation:
The local charity collected an amount of $38.2 million last year. To write this amount in scientific notation, you first express it as a number between 1 and 10 multiplied by a power of 10. In this case, $38.2 million translates to $38,200,000. Written in scientific notation, this amounts to 3.82 x 10^7.
Scientific notation helps in representing very big or small numbers for easy comprehension and space-saving. Scientific notation is widely used in fields such as Astronomy and other sciences because they often need to deal with large numbers like the ones we are discussing.
