The accompanying table gives the number of copies sold for 30 top-selling novels. Use data given in the table to construct a frequency distribution with a first class (in millions) of $0-99$.
\begin{tabular}{ccc}
Copies Sold (millions) \\
500 & 90 & 70 \\
300 & 87 & 65 \\
150 & 85 & 65 \\
150 & 85 & 60 \\
130 & 85 & 45 \\
103 & 80 & 45 \\
100 & 80 & 40 \\
100 & 75 & 40 \\
100 & 70 & 40 \\
100 & 70 & 30
\end{tabular}

Answer
The frequency distribution table is as follows: Copies Sold (millions) Number of Books 0-99 6 100-199 4 200-299 1 300-399 2 400-499 1
Step 1 ：Determine the range of the data: 500 - 30 = 470
Step 2 ：Choose a width for each interval, such as 100
Step 3 ：Construct the frequency distribution table with the given intervals
Step 4 ：Count the number of values that fall into each interval
Step 5 ：Fill in the frequency distribution table with the counts
Step 6 ：The frequency distribution table is as follows: Copies Sold (millions) Number of Books 0-99 6 100-199 4 200-299 1 300-399 2 400-499 1
