Subject: percents The last week of a month a car dealership sold 12 cars. A new sales promotion came out the first week of the next month and the sold 19 cars that week. What was the percent increase in sales from the last week of the previous month compared to the first week of the next month? |
Wang,
Percentage increase is the increase as a fraction of the starting value, expressed as a percent. Thus if the dealership had sold 20 cars in the first week of the second month rather than 19 the percentage increase would have been
(20 - 12)/12
100 = 66.7%
