A store reported total sales of $385 million for February of this year. If the total sales for the same month last year was $320 million, approximately what was the percent increase R in sales?
Choose the correct answer:
A) 2%
B) 17%
C) 20%
D) 65%
E) 83%
Last year's sales = $320 million;   This year's sales = $385 million;   Increase R = $65 million.   Now, 20% of $320 million is $64 million, which is very close to actual increase of $65 million.   Answer: 20%.
