The us based motorcycles says that it expects to build 147,000 motorcycles this year, up from 137,000 last year. find the percent of increase in production.

The answer should be about 7.3%. You can divide 147000 by 137000 to get about 1.0729. Subtract the one (as it represents 100%) and then convert the decimal into a percent. So 0.0729 would convert to 7.29%, but typically this would be rounded up to 7.3%. If it does not say to round up then don't.
