An online bookstore reported total sales of $768 million for the first quarter of the current year. If the total sales for the first quarter of the previous year was $640 million, what is the percent increase in total sales?

(A) 5%
(B) 15%
(C) 17%
(D) 20%
(E) 80%



The increase in the sales(reported) of the online bookstore is $768 * \(10^6\) - $640 * \(10^6\) = $128 * \(10^6\)

Therefore, the percent increase in total sales is \(\frac{$128 * 10^6}{$640 * 10^6} * 100 = 128 * \frac{10}{64} = 20\)% (Option D)

New sales total: 768 M
Old sales total: 640 M

Percent increase:
\(\frac{New-Old}{Old}*100\)

\((\frac{768-640}{640}*100(=(\frac{128}{640}*100)=\)

\(.20 * 100 = 20\)%

Answer D

New Sales = 768 M
Old sales - 640 M

640 M = 100% , so 10% = 64 M

New - Old = 768-640 = 128 , which is nothing but 2 times 10% of old sale. The answer is 20%.

Ans: D
