Elena was shopping for a new bathing suit. She found one she really liked. It was for sale at 40% off. In order to figure out how much the discount was, she needed to convert the percent into a decimal. What is 40% as a decimal? (I solved that part) if the bathing suit costs $36 and was 40% off, how much did Elena pay for it?

There are two major tests of readiness for college: the act and the sat. act scores are reported on a scale from 1 to 36. the distribution of act scores in recent years has been roughly normal with mean µ = 20.9 and standard deviation s = 4.8. sat scores are reported on a scale from 400 to 1600. sat scores have been roughly normal with mean µ = 1026 and standard deviation s = 209. reports on a student's act or sat usually give the percentile as well as the actual score. the percentile is just the cumulative proportion stated as a percent: the percent of all scores that were lower than this one. tanya scores 1260 on the sat. what is her percentile (± 1)?
