Question

The number of different cars sold in some country rose from 210 in 1997 to 277 in 2007. Find the percent increase. Round to the nearest whole percent.

Answer 1

Find percent increase by subtracting the amounts and dividing it by the old amount, then multiply the result by 100 to make it a percent.

Increase= (277-210)/210

67/210

Then it ends up as 0.319047619...

Multiply that by 100 to make it a percent, which is..

31.9047619..

Round it off, and you get..

32%!
